Thanks John. They are non cartridge forks. I swapped to the XR forks for the front disc brake. The TT came with a drum brake front end. I'm guessing 88-90 was the model year because of the red fork boots. Honda switched to blue boots in 91. The Belgarda never came to the U.S. Even the TT/XT Yamahas never were as popular as the XR/XL Hondas. Aftermarket Yamaha TT parts are VERY hard to find here. Thanks again, Kelly.
