motorcycle question

is the vex 1300 same frame size as the 1800 or is the 1800 a bigger frame

This might help you. If you own a 1300 and are thinking of upgrading to an 1800 motor, I would think long and hard on that.

I own a Suzuki S83 and a Suzuki Hyabusa (1300 rice rocket). They have both been used by some of the ladies on Terb for outdoor photoshoots. Remote locations of course!
