Suzuki PE250 model history
1977—1982

I have put some Suzuki PE 250 info 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.

Suzuki followed the successful RM motocross bike series with a spectacular enduro, the PE250 in 1977. Suzuki gave the off-road crowd both barrels. These bikes are one-hundred percenters, no corners cut.
