X - 5 Squared Dual Pulley Upgrade Kit

This is proper good, a very worthwhile upgrade for anyone with an X5^2

And if you're not Squared by now, for heaven's sake go see Lesro or us and get with the program!!!

The new Dual Idler Kit will fit original X - 5s with a bit of drilling & tapping on the idler bar. Doesn't take much time and you neednt be perfectly accurate. It's like government work: anything close will do.

Is it a big problem with the belt skipping on the X-5 ?

Far from it.
Belt skip is expected and harmless on extreme braking, and super-accelerating with insane motors. Don't be alarmed.

The dual roller does reduce the skipping, but this has a benefit in you can run the belt looser to go faster ;)
