В
1975 году
Suzuki
впервые представила свои успешные модели RM для мотокросса.
Наиболее крупная из них RM500, была введена в 1983 году, которая
имела черную раму, черные гофры вилки, черные сиденья и немного
другой топливный бак с знаками, отличными от
модели
1984 года.
'83 RM500 отличается от 82 RM465 в основном увеличенным размером
двигателя. Во всем остальном, кроме незначительных косметических
изменений, мотоциклы были очень похожи.
В то время это был крупнейший motocrosser от Suzuki, до этого
самый большой
был RM465. Полностью плавающая задняя подвеска, которая была
впервые использована в командных гонках по мотокроссу, пошла в
серию RM в 1981 году.

Suzuki
introduced its succesfull RM series of motocross models in 1975.
The largest of them all, RM500, was introduced in 1983, even
larger thanthe 1981—1982 RM465 and its precessor, the 1978—1980
RM400.
At the time it was the largest motocrosser from Suzuki (when
RM400 was introduced in 1980 it was the largest). The
Full-Floater rear suspension was first used by the works road
racing and motocross teams. It went into the RM series in 1981.

The
1982-year's RM465D was practically the same bike as the
1981-year's RN465X. In fact, even t he '83 RM500 differed from
the '82 RM465 mainly from the increase in engine bore size.
Other than minor cosmetic changes, the bikes were very similar.

The largest Suzuki motorcrosser of the seventies. Still air-cooled
with conventional, but laid down twin shocks at the rear.
The U.S. sales brochure from '78 says this: ”Even if somebody could
build an engine as good as the RM-400 Power Reed, they still
couldn't beat Suzuki's air forks, aluminum works type box section
arm, and laid dow, forward mounted gas-oil shocks (with reservoir)
for total performance. Conical hub in front—full floating brake and
magnesium hub panel in the rear.”

on the vintage-suzuki.com website.

New graphics but basically the same machine as the '79 RM400N. Wider
5.10-18 rear wheel, more ground clearance, a little heavier. You
will find more specs on the RM400 magazine articles page (Dirt Bike
article, May 1980).
The pictures of the Massimo Pipino's RM400T are taken recently and
the bike is not 100% original but quite close.

Comments: ”This is the bike I used to ride in vintage MX
championship. It's a Suzuki RM400. It was built in 1979 and I bought
it two years ago.
It is in its original shape. The only thing I replaced is the
handlebar, because i prefer the shape of Renthal.
The bike is very easy to ride, powerful but not brutal like, for
example, the later KTM 495/'91. It's not too heavy and you can ride
it like it was a 250cc.
Great bike!”

Piston
Specifications
The engine used a two-stroke, single-cylinder design. The bore by stroke of
the single piston measured 3.03 inches by 3.14 inches. The piston had a
7.6-to-1 compression ratio. The piston design featured a piston port and
reed valve operating system, which was a common design for dirt bikes and
other ATVs. The piston and reed valve system was attached to the crankcase.
The gasoline intake system sported a dual-inlet design. Other piston
features included four scavenging pots, which provided the engine with
above-par scavenging and airflow capability. To further improve combustion
and efficiency, the cylinder used a squashed-dome design shape.
Engine Specifications
The 1976 Suzuki RM370 engine had a piston displacement of 372 cc. Maximum
power output measured 42 horsepower at 7,000 rpm, while the peak torque
potential measured 33.7 foot-lbs. at 6,000 rpm. The standard clutch used a
wet, multi-plate with aluminum and fiber-discs design. The air filtration
system featured an enhanced oiled polyurethane foam air-filter. The ignition
used Suzuki PEI Pointless Electronic ignition technology, and the starter
featured a non-primary kickstart.
Fuel and Carburetor Specifications
The engine also sported a Mikuni VM36SS carburetor fuel system. The
carburetor's main jet specification was set at 300. The needle jet was R2,
and the needle was a 6FJ6-3. The slide cut was set at 1.5, and the pilot was
No. 50. The factory position of the air-adjusting screw was 1.5 turns open.
The float level measured 2.16 inches. Suzuki recommended using premium-grade
fuel, and the gasoline-to-lubrication mixture amount was 20 to 1.
Dimensions
The 1976 Suzuki Rm370 had a length of 84.3 inches, a width of 38.8 inches
and a height of 47.2 inches. The ground clearance measured 10.4 inches, and
the seat measured 35 inches high. The swing arm had a length of 19.5 inches.
The dry weight of the bike was 235 lbs. Weight was 44.8 percent on the front
and 55.2 percent on the rear. The fuel tank held 2.1 gallons. The standard
front tire dimensions were GS-45F 3.0 by 21.0 inches, and the rear tires
were GS-56F 4.5 by 18.0 inches. Front brakes featured a 5.11-inch
cable-operated design, while the rear used a 5.9-inch cable-operated design.
Design and Features
The front suspension used a Kayaba telescopic fork with 8.66 inches of
stroke, and 247 cc of oil capacity. The rear suspension system used Kayaba/Dr.
DeCarbon nitrogen gas shocks with 8.62 inches of axle travel. The dirt bike
frame featured a chrome, semi-double cradle design. The standard
transmission was a five-speed manual with a straight cut, primary-drive
ratio of 2.384 to 1. Gear ratios were as follows: first: 2.071 to 1, second,
1.624 to 1, third: 1.263 to 1, fourth: 1.000 to 1, and fifth: 0.869 to 1.
The final drive had a 13-tooth counter-shaft and a 50-tooth rear sprocket.
