This belt will fit our "Big Wheel" Scooters, BUT!! (It is weak) compared to the 5m-18 factory belt. We have even found that slight Shimming to Xcooter Thunder a.k.a. Raser Big Wheel a.k.a. PanthR models that have 102 tooth aluminum wheel sprockets with lip out can be shimmed behind sprocket to allow for running even 5m-20 belts. Not sure about Salorr Big Wheel model using 5m-20 yet without fipping both sprockets and maybe replacing wheel sprocket from plastic to aluminum 102 tooth sprocket from Chuweng.
