Read all the reviews. Sounds like it’s the perfect fit for my Motobecane AV10. Got it installed but no bueno. It’s too wide and it ate up all my variator action. The motor needs room to move back and forth for the variator to do its job. This belt needs to be longer. Used my tears to help get it off.

I put this belt on my AV10-converted 40t, and it seemed WAY short. Like it started halfway variated. so I took it off.
Then I installed a varplus, and my 4L320 belt seemed WAY long....
So I reinstalled the X-Belt.... and.... PERFECTO! Thanks Treats.

i had this belt on the er2 doppler fixed pulley + stock variator and it was wayyyy too wide and wayyyy too short, to the point where it cut my variation in half. it also kept flipping inside out when i took it to full throttle and got ripped up real quick. thought my engine wasn't spaced right, but i checked it and it was. idk maybe i got a weird one. gonna stick with the ax30.
Just too damn wide 
Great with the Varplus
