Мотоцикл Suzuki RM250
 Спросите любого профессионального гонщика по мотокроссу, в чем секрет
победы на соревнованиях. И Вы узнаете, что секрет не только в количестве
лошадиных сил, когда байк взмыл в небо, и не только в отличной ходовой
системе, если байк застрял в грязи. Секрет победы в разумном балансе этих
показателей. Именно эта золотая середина и заложена в Suzuki RM 250.
Оцените его мотор, в этом модельном году он получил дополнительную прибавку
в мощности и больше тяги на средних и высоких оборотах. Выхлопная система
также увеличена и перенастроена и теперь состоит из одного клапана вместо
2-х в предыдущих моделях. Новая, облегченная расширительная камера теперь
оснащена укороченным глушителем и совершенно новым выпускным клапаном для
того, чтобы достичь мгновенной реакции на рычаге акселератора. Зазор между
цилиндром и поршнем также удалось сократить, таким образом, удалось
увеличить долговечность двигателя и уменьшить шумность. Процесс
переключения передач теперь стал более плавным, а новая конструкция КПП
сделала ее более долговечной.
Под новые характеристики двигателя совершенствованию поддались и ходовая и
тормозная система. Поэтому подвеска отлично показывает себя на любом
бездорожье, особенно на серии часто повторяющихся холмов. Новая рама
клиновидной формы стала более жесткой на скручивание. Местоположение задней
подвески изменилось таким образом, что клиренс мотоцикла увеличен, поэтому
управлять им стало удобнее особенно в условиях полного бездорожья.
Новый Suzuki RM 250 просто неубиваемая комбинация мощности и управляемости,
особенно в условиях полного бездорожья.
Особенности мотоцикла:
-
Полностью новый мотор уменьшился в весе и размерах, обладает большими
мощностью и максимальным крутящим моментом, а также выразительным
"подхватом" на средних оборотах
-
Головки цилиндра с уменьшенным диаметром и толщенной стенки уменьшают
сухую массу мотоцикла.
-
Карбюратор дополнительно оснащен сенсором положения дроссельной
заслонки для лучшей отдачи от рычага акселератора, особенно на низких
оборотах.
Кроссовый мотоцикл с 2-тактным двигателем рабочим объемом 250 куб. см.

With the '83 RM250, fork diameter was increased to 43mm. Engine changes
included a different cylinder head (revised squish band), and increased
crankshaft inertia. Unfortunately, these changes were a step backwards
as the '82 had a more potent powerband. Minor cosmetic changes were the
only visable differences.

Suzuki announces that they use their own SBC (Suzuki Boron Composite)
coating on the RM250 engine. It is lighter than normal metal and
radiates heath more easily. The more obvious improvement is more
noticeable. For the first time, the RM250 has disc brakes both front
and rear. The maximum power output is slightly over 50 horsepower.
Also, the '86 RM250G had a new and stronger frame. Suzuki says that the
amount of frame parts has been decreased to less than half. The Full
Floater rear suspension was new, both swing and the link system."An
eccentric cam in the link system for increased progressiveness and
improved damping. Lower seat height despite of the higher ground
clearance.”
The engine was coated Blue.

Suzuki says that the power and torque has been increased for the
2004-year's model. Redesigned and lighter flat-top piston, redesigned
exhaust ports and piston ringsare some of the other improvements to the
engine. The carburetor has been rejetted.
The frame, suspension and brakes have all been improved for the K4
model. Both front and rear shock absorbers are new, the rear suspension
linkage has been redesigned for better progressivity, both front and
rear brakes have been improved and the front fork is thicker and the
outer fork tube longer than in the previous model. The frame has the
same design than before but is made a bit stronger. Some minor
improvements on the rear wheel and clutch cabel adjustement.
The footpegs have been moved 10mm (0.4 in) backwards, the handlebar 7mm
(0.3 in) and the seat has been redesigned and is made 10mm (0.4 in)
lower than in the previous year's model.

Мотоцикл Suzuki RM125
Позвольте представить Вам мотоцикл Suzuki RM 125, за которым давно уже
закрепилась слава одного из лучших в своем классе. Но инженеры Suzuki Motor
Corporation не стали останавливаться на достигнутом. В новой модели удалось
уменьшить вес, увеличить мощность и улучшить управляемость.
Одно из главных новшеств Suzuki RM 125 абсолютно новый выпускной клапан,
который направляет выхлоп прямо через впускной канал. Но на этом новации не
заканчиваются.
Карбюратор Suzuki RM 125 также улучшен для максимальной эффективности рботы
в любых скоростных режимах. Также уменьшилось просвет между цилиндром и
поршнем это увеличило срок службы двигателя и уменьшило шумность. После
доработок также увеличен срок службы КПП.
Чтобы полностью соответствовать новым динамическим характеристикам
двигателя, инженеры Suzuki улучшили и ходовую часть и подвеску. В
результате не только увеличился клиренс мотоцикла, но и центр тяжести
переместился в сторону передних колес. Это только лучшим образом отразилось
на управлении мотоциклом в узких поворотах. Прибавьте к этому высокую тягу
на низких и средних оборотах, и Вы получите мотоцикл просто созданный для
уверенных побед на самых сложных триалах.
Кроме всего прочего, рама мотоцикла усилена вокруг рулевой стойки теперь Вы
можете смело и уверенно брать любые подъемы на трассе. За счет применения
легкосплавных материалов, уменьшился вес передней вилки.
Итак, оседлайте этот один из лучших кроссовиков, и пусть Ваша карьера
профессионала начнется именно с него.
Особенности мотоцикла:
-
Новый цилиндр с улучшенным каналом продувки выпускным каналом.
-
Установлен карбюратор Keihin PWK38PWJ с новым обходным контуром
стартера.
-
Пластинчатый клапан карбонового типа обеспечивает мотоцикл резкой и
четкой реакцией на ручке акселератора, оптимизировав процесс сгорания
топливной смеси.
-
Хромомолибденовая рама с подрамником из алюминия уменьшает вес и
облегчает обслуживание.
-
Уменьшенный зазор между поршнем и цилиндром для улучшенного давления
в цилиндре и тяги на средних и высоких оборотах, увеличенный срок службы
и уменьшение шумности.
-
Облегченная цепь DID DMA2.

Suzuki RM125 2004
Suzuki RM125 2003
The 2003 RM125 is the latest
version of the racebike that made Travis Pastrana famous, with a broader
power band and better throttle response, producing significantly more
power and torque between 6,000 and 8,000 rpm with no loss of high-rpm
performance. That translates into better lap times with quicker
acceleration and better rear-wheel traction.
Much of the power band improvement came from redesigned, better-sealing
exhaust-port valves and more precise control of those valves. A new
actuation system controls how far and how fast the valves open and close,
matching exhaust port timing and area to engine rpm to improve throttle
response and power delivery.
New ducts in the side covers feed cool air to the airbox, while a new
rubber cover keeps air warmed by the radiator from entering the front of
the airbox. The subframe cross-brace tube located behind the airbox is
now round in cross-section instead of square, improving air flow to the
airbox and also slightly reducing weight. The radiator is about 10%
larger, with 11 rows instead of the previous model’s 10 rows.
A new press-fit gearshift stopper pin, a stronger shift-cam stopper
spring and a shouldered shift pawl pin all contribute to more precise
shifting. The shouldered shift pawl pin fits into the coils of the shift
pawl spring, instead of sitting on top of the end of the spring,
reducing side-to-side play.
The RM125 built its reputation with handling to match its engine
performance, the type of handling that gives a rider a choice of lines,
inside or outside, to make a critical pass. It’s the type of handling
that comes from the right combination of geometry, frame rigidity and
suspension response.
The 2003 RM125’s single-backbone, double-cradle high-tensile steel-alloy
frame has detail refinements, while the mid-stroke response of the front
forks and rear shock has been improved. Slightly stiffer fork springs,
0.42 vs. 0.40, allow the use of less compression damping, and reshaped
and resized compression damping valves help smooth mid-stroke response
and improve response over small bumps. The inner cartridge rod and pipe
nut are now made of aluminum alloy instead of steel, reducing weight,
and the spring guide bush is now metal instead of plastic, increasing
durability. The fork cap head is now hexagonal instead of oval and can
be turned with a conventional wrench instead of requiring a special tool,
simplifying maintenance.
The piggyback-reservoir rear shock has revised rebound and compression
damping, again aimed at improving mid-stroke and low-speed response,
improving acceleration traction. The shock shaft has been hardened for
better durability, and the reservoir cap head is hexagonal instead of
oval.
The brake discs have reshaped holes to reduce squealing and pad wear
while improving braking power and feel, and the rear brake pad material
provides more stopping power and longer pad life. The center and lip
sections of front wheel rim are thicker for better durability and the
reshaped front wheel spacer helps locate the axle properly when the
wheel is installed.
The foot peg mounts are redesigned to not pack with mud on a wet track,
and the rear brake pedal mount has been moved up to keep it from
dragging on the ground in rutted corners. As a result, the rear brake
lever can be straighter, slightly reducing weight. The foot pegs are now
10mm longer for better boot grip.
The seat is reshaped, lowering the riding position by 7mm, and the seat
cushion foam is about 8% firmer to compensate for the reduced thickness.
The seat cover is now made of thicker vinyl, increasing durability.
The 2003 Suzuki RM125’s brilliant chrome side graphics stand out against
its bright Suzuki Champion Yellow color, and an extra-thick clear
plastic lamination helps keep those graphics looking good. The number
plates are white, ready for the application of racing numbers.

Air-cooled models, 1975—1980
1975 Suzuki year code: M
|
Suzuki introduced the RM series of motocross models
in 1975, these replacing the TM models. The range quicly stretched out
from 50 to 400cc and became very successful. A few years later the Full
Floater swingarm was introduced and water-cooled engines came along in
1981 — and the developement of the RM models continues even today.
The first model version of the RM125 had "downpipe", the exhaust pipe
placed under the engine. The TM125 was discontinued and instead came
the RM125. When tested against the competition in the US market the
RM125 was found not powerful enough to compete with the Honda CR,
kawasaki KX and Yamaha YZ models and had to be quickly modified before
mid year 1975. The model name to the revisited model was RM125S.
To make the bike faster Suzuki did some interesting alterations in the
following areas of the engine: they reworked the porting of the
cylinder barrel massively, all ports were opened significantly and they
appeared to have been finished by hand when viewing the cylinder. The
new hand built exhaust pipe for the RM125S was slightly larger in
diameter and made of many rolled steel pieces welded together, not
stamped with two londitudal folded seams like the M model. The stinger
bulb was also welded on at the end of a slim diameter pipe with a stiffener
rib above and below it to stop cracking where this pipe met the end of
the expansion chamber.
The headpipe also still carried the OEM chrome exhaust collar, but now
used extra "L" shaped pieces placed under the bolt heads, these 'ears'
each held one end of the springs that kept the pipe in place to the
cylinder head.
The pistons skirt had two holes drilled into it to help cool the thin
exhaust port bridge section as the new exhaust port was now quite wide,
the head gasket material was also slightly different.
The S models Mikuni carburettor was also quite larger and didn't have
the tall top cap as the M model, and the carburettor intake rubber/alloy
pipe was also larger and carried an adapter plate. The new carb had
increased jetting values and a special needle valve orifice with three
extra angular drilled holes to allow fuel to bypass the lower needle
valve body into the bigger float bowl.
The newer and bigger CDI unit for the S version was now mounted onto
the front of the frame headtube with a bracket instead of in front of
the aircleaner case as with the M, and finally the air cleaner case was
altered to accomodate a bigger rubber connector boot. To let the owner
know they had bought an 'S' model, the fuel tank had a decal affixed
right below the filler opening that said RM125"S".
As noted, the power output went up to 26hp, and this was enough to allow
it to run with the CR, KX and YZ models that were beating the M model.
The S model only lasted for about four months (later in some countries,
it was sold as a 1976 model at least in Finland) as the new A model was
being tested for '76 and the S therefore never sold in large quantities.

 These
two pictures or the rare RM125S were sent to me by Allan Tucker,
Barbados.
“You can see quite clearly the CDI box mounted on the steering column
on the bike and how the hand made pipe looked as well as the non tall
cap carb. The small dents in the stinger bulb were there when I bought
the bike, but the bigger impression in the pipe lower down is for the
kick starter to pass when starting,” Allan says.

Alan Tucker sent me some RM125S spec carb data to add to this page
against the standard RM125M. Alan writes: “Just look at the size of
this thing and its main jet compared to the M models tiny 28mm one with
a #180 main, even the faster A model only had a 32 mm carb when it was
released, but the same size 280 main jet was retained.
In the RM125S carb the two floats were separate from the arm, riding up
and down on two vertically mounted brass shafts pressed into each side
of the bottom of the float bowl. They also had short pins fixed onto
the side portion that touched the separate arm unit to register float
level. For some unknown reason Suzuki choose to use bright PINK poly
hoses for the overflow tubes on the S model, you could not miss the
colour of these hoses.”

The RM125A with six gears was distinguishable a mile away, the first
Suzuki motorcrosser with an up-swept exhaust pipe. The bike was very
fast and competitive. In 1976 there were two different models available;
the RM125A and the (rare) RM125S. The models had the same piston
displacement but were quite different motorcycles. While the RM125A's
engine had reed valve, the RM125S piston valve. It also had different
piston rings, larger carburrettor and different gearbox etc. The S
model had a 5-speed gearbox. There were differencies even in the
suspension. The most significant difference between the models was that
the RM125A had a high-drawn exhaust pipe, while the RM125S had it drawn
under the engine.
The 1976 RM125S and the 1975 RM125M were almost identical machines.
Probably the RM125M had a welded on muffler, and the RM125S muffler was
removable by a top and bottom spring. There were some carburetor
changes, and a gain of three horse power in the S over the M model.
In Australia the RM125A came very late and weren't available until the
1977 Motocross season.
I haven't managed to find a picture of the
RM125S anywhere so I used a RM125M picture instead. I will replace the
picture as soon as I can find one of the S model.

The only things that stood out to tell the B model apart from the
previous model was the leading front axel and the “muffler on the end
of the exhaust was a fraction longer. Inside the engine the bore and
stroke was changed to a slightly smaller bore with a longer stroke to
help bottom end performance. It was now a square 54 mm x 54 mm bore
engine.
In Australia the RM125B came very late and weren't available until the
1978 Motocross season.
