The [[Suzuki|Suzuki]] RG250 Gamma was a two cylinder parallel, water cooled 250cc [[two-stroke|two-stroke]] motorcycle produced by Suzuki from 1983 to 1987. One of the major features of the RG250 Gamma was its incredible power to weight ratio. Able to produce up to 45+ bhp at 8,500 RPM and 38.4 Nm torque at 8,000 rpm, weighing in at roughly 130 kg. The RG250 Gamma was the very first mass-produced motorcycle to have a lightweight aluminum frame and racing type aerodynamic fairing. | |||

The Gamma also had a very advanced 'Full Floater' suspension system for its time, with the first Mk1s having 'anti-dive' front forks (which locked the front forks under hard braking to stop them diving). Due to this, the bike was dubbed the first street legal racer.

The RG250 Has a Liquid-Cooled Parallel twin engine with 46 hp output at a relatively low 8600 rpm. The RG250 Gamma is a two stroke, but water cooled and in a brilliant frame, with 6 speeds lightweight aluminum frame, full floater suspension, it is a quick motorcycle which handles very well. It also has A.N.D.F., a proprietary [[Suzuki]] technology which was first used on the [[Suzuki RG500|RG500B]]. With a dry weight of way under 300 lbs. This bike is unbeatable in the tight stuff. This bike was made in special '''WALTER WOLF''' editions as well. | The RG250 Has a Liquid-Cooled Parallel twin engine with 46 hp output at a relatively low 8600 rpm.

==Engine== | |||
The engine was a [[liquid cooled]] twin, two-stroke. A 54.0mm [[bore]] x 54.0mm [[stroke]] result in a [[displacement]] of just 247.0 cubic centimeters. Fuel was supplied via a membrane & variable discharge openings. | |||
==Drive== | |||
The bike has a 6-speed transmission. Power was moderated via the Wet Multiplate. | |||
==Chassis== | |||
It came with a 100/90-16 front [[tire]] and a 100/90-18 rear tire. Stopping was achieved via dual disc in the front and a single disc in the rear. The front suspension was a Telescopic, Coil Spring, Oil Damped With Anti-dive while the rear was equipped with a Full Floater, Gas/oil Damped, Spring Pre-load Fully Adjustable. The RG250 Gamma was fitted with a 4.49 Gallon (17.00 Liters) fuel tank. The wheelbase was 54.49 inches (1384 mm) long. | |||

The diameter of the front forks was increased from 36 to 38 mm (1.42 to 1.50 in.), the brake discs were enlargened and even the tire sizes were changed (from 100/90-16 to 110/80-16 at the front and from 110/80-18 to 120/80-17 at the rear). The changes made the '87 model felt more rigid and less nervous than the earlier models. | ||
