Jan Babendererde's kick ass J&C Motoconcepts' Yamaha TT550 Special
notes from Jan: TT500 frame with custom subframe to accept RaceTech SG3 monoshock and YZ125 seat. Modified steering angle; Stroked motor (547 ccm); High compression piston; Web cam; titanium valve springs; Protec Exhaust; 83 YZ 490 forks with Racetech springs and gold emulators; Full Circle rims and Buchanan spokes. This is a great picture. Might want to say TT550. I would like to mention, that Chris Hughes did all the fabrication and welding.
