The ONLY reason most bikes use chains and some belts is because it's cheap. Using a driveshaft requires extra parts and introduces a bit more complexity which is counter to many practicalities of motorcycles.

The reason cars do not use belts is because they simply weigh too much for a belt to handle the loads for long before snapping. They are utilized in key areas where the stresses aren't greater than they can handle without sacrificing durability. Chains would be the alternative but with driveshafts being so proven in all areas, it's not practical to run chains with hundreds of parts, any of which might fail far more easily than a driveshaft.

CVT transmissions which are growing their presence quickly in 1:1 vehicles. There are belt and chain driven variants.

Anyways. The o.p of the belt comment is obviously trolling. The belt designs have been proven.

All Yokomos have been belt driven until the BMAX-4.

Love that Hara is with Yokomo. He has major skillz as he can drive everything. He has been in a funk per 10th scale off-road however I have no doubts that we will soon see Hara back in the Master Zone. He just recently won Malaysias biggest sanctioned 8th scale nitro buggy championship.

I was in the process of removing the front trans, unscrewed the front bumper and removed it to get to the four screws that go into the transmission and what seemed like a hand full of dirt dropped out of the front transmission. I think the front bumper needs to be made out of a stronger material that wont wear out as fast.

Sorry to bring up an old post. Did you pinpoint the cause of the binding? I bought a used YZ4 and it has me a bit stumped as to why I have sooooo much of a bind. I've replaced the centre layshaft and pulley, added the narrow rear belt and used the rear belt pulley on the front. I'm at the stage of wondering if the chassis itself is tweaked.

Go to Shapeways and look up BRC shop. He has a 3D printed front bumper/skid that secures to the suspension mount using 4 screws. Much better than the factory part. Put a little grease around the perimeter thus will create a super seal hence not dust in your tranny.
