Product Details
A 16.25 inch long, 1.25 inch diameter titanium rear axle built for mini bike drag racing. It uses the standard 1.25 inch hub and sprocket carrier hardware you already run, so it drops into a mini bike drag build in place of a steel or aluminum axle without changing bearings, hubs or carriers.
If you have already chased weight everywhere else, the rear axle is the last big piece of rotating mass left. Weight at the axle has to be accelerated and stopped every pass, so taking roughly a pound and a half out of the driveline shows up in sixty-foot times in a way that the same weight bolted to the frame never will. Titanium also gives you the fatigue life and corrosion resistance to leave it in the bike season after season.
This axle starts as a solid billet piece and is 100% machined inside and out. No tubing is used anywhere in it, because tubing is not always truly round — and an axle that is not round shows up as runout at the hub, sprocket and brake rotor.
