Are there 3rd-party, after-market (i.e. non-Kyosho) parts?
• There was an American company in the early 1990-91 that made some aluminum accessories for the bikes. They eventually have run out of business. I don’t know of any other company that makes accessories, at the moment. (Update Oct. 2003:) At ebay.com, once again, I found quite a lot of upgrades made by TopCad and GPM, mostly in aluminum (swingarm, wheels, brake discs, front steering stem, oil-filled forks and shocks etc), ball bearings and other goodies. Any info, welcome. • Are there many upgrades for them? • Try to get a hand on a recent Kyosho catalog. There is a page full of them! Here’s a quick list (Availability was never good, though…) Old Model New Model Oil filled forks Oil filled USD forks – Steering parts set – Chrome-plated frame 270 mAh Battery 600mAh battery There are some parts that can be interchanged between old and new models. (New models are the ones with the leaning rider). Rear oil shock, Reinforced Gear set, Ball bearing set, Hard pinion set, Light flywheel.
