When a friend came to us asking if we could road legal his old motocross bike the answer was yes I suppose so. After several infuriating phone calls to the DVLA it was thought that it would be easier to reframe the bike if a frame for a 250 exc could be sourced, using the more powerful motocross engine after finding one on ebay the project was started, but when the frame turned up it was for a 200exc which uses the 125 sized frame after comparing the frame all the suspension pick up points which where the same it was found that the engine didn't fit because the gearbox is bigger the answer was to get the angle grinder out!
