Suzuki RG250E 1978—

I have put some RG 250E information on this page. The page is still under construction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

From GT250 to RG250 RG250 and it's sister model RG250E were launched 1978, simultanously with RG125 and RG185, formerly knows as GT125 and GT185. But RG250 wasn't just a GT250 with new paint job. It was a completely new machine. Many 250 cc motorcycles at the time were heavy and clumsy because the frames weren't often designed for the small engine. It was common to put a 250 engine into a 350 or 400 frame. This wasn't the case with the RG250 (known as X-7 or GT250-X7 in many countries outside Japan). While the 1977 GT250 was a light mororcycle with its 146 kg (321 lbs) the new RG250 was 20 kg (45 lbs) lighter, making it super lightweight. The 30 hp's of the RG250 made the bike quite sppedy, thanks to the good power/weight ratio. It's no rocket, though. According to a Japanese test the bike made the 1/4 mile (400 m) at 14.2 seconds. The RG250 kept the Ram Air cooling system of the GT250, that pressed the air through the cylinder head ribbons, a quite effective cooling system and it actually works. The RG250E had alloy cast wheels, the RG250 had classic steel wire rims. There was also some differences in the colors, otherwise it was the same model.
