I take my hat off to you ,sir, beautiful riding! As somebody who's had a couple of GPXs I have to ask if you're really getting those lean angles and the traction out of bends on a standard 140 section rear??😃
The wheels have been replaced with 17 inch wheels front and rear. The front suspension is an inverted fork from a ZXR750, and the rear is genuine. The wheel sizes are 3.5J in the front and 5.5J in the rear.
