How to gain top speed..everyones input...BELT ONLY

[veeemdoubleu]

Ok i want to increase the top speed of my XB12R or any of our belt driven bike, NO I DO NOT WANT TO CONVERT IT TO CHAIN.

Anyone makes after market rear sprocket and belt combo?? will any other harley belt and sprocket fit the bike for top speed?

WHat about internal gear changes? anyone makes taller 4th or 5th gear?? or even a 6th gear?? is that even possible?

Sprocket size same for all XB???

please give your input.

I don't know enough to give you an answer, but here's a thread that might interest you: Difference in Pulleys

The easiest way to gain top speed while keeping a belt is.... are you ready for this?..... an 1125R conversion!!

Dave, you're on a role today.


I got more top speed by scratching out the 120 on my Speedo and wrote 360.

lol ok time for a serious answer... Put some NOS in the tank (And no not the energy drink), This should help you gain 50% horsepower lol

maybe some "Full Throttle" instead?

ok seriously.... yeah custom machined pulleys and raised rev limit, wider tires(makes the diameter larger), and maybe some jet engines like this dude has.

Trojan Horse offers A Free Spirit pulley setup that drops your rpm by 10% to give you better top end.

The pulley looks sweet and lines up with the wheel spokes to streamline the pulley, but costs about $750.
