– Fast Eddy Bearings Full bearing kit for Atomik MM450.
– Custom wheelie bar.
– Foot pegs removed and rider legs held close to bike with rubber bands.
– The steering is limited so the bike arcs the fastest corner on the track without over steering. The throttle is limited to be comfortable for me, usually 75 to 80%. The brakes are set on the soft side so I can pull full brakes without the front or rear wheels locking, the rear will still drift out while turning in.
