Ok, I know there are alot of posts on 6 speed transmissions for the Vrod, but I have a question for you more knowledgeable types. I did a google on 6 speed transmission for vrod and it took me to jpcycles.com to a generic right side 6 speed transmission. Just wondering if this would work on a 2011 Nightrod Special? Would be nice to know before I spend close to $1k.
Can you change the gears themselves? I think V/H CHANGE THE 2ND gear???
Yes they did, but this gear is designed to facilitate racing, the stock 2nd gear has more narrow teeth in a helical cut which have been known to break under racing conditions.
VH, makes two versions of 2nd gear one which complies the Destroyer setup and is an acceptable substitute to remain in SPEC compliance with VRD class racing rules. The gear on the far right is the new VH 2nd gear.
The other, also a straight cut gear is designed for street bikes that might be under greater stress due to BiG bore, Nitrous or Turbo applications that are being raced.
The ratio changes on these gears are negligible.
I'm with the other guys who suggest changing your final drive ratio to get the high gear engine RPM's down, but don't compare the RPMs to an EVO or TC, the Revolution engine is much happier at a higher number, get acclimated to it.
Even if you could find a vendor to make custom gears, you won't have clearance in the case.
Thats the answer I've been looking for for a good while! I asked this very same question about a year or so ago--and asked if there were any physical limitations inside the tranny case to prevent a taller 5th from being installed.... money considerations for the gear itself aside... nobody ever gave me a straight answer. What part causes the interference? Is it just a very tight tolerance to the case?
Check out the photo above. I circled the edge of fifth in the attachment. This the gear that needs to grow and its opposing gear to shrink. If I am not mistaken, 5th is part of the shaft meaning you would need to manufacture the whole output shaft...I could be wrong.
Anyway, in my attachment I circled where the gear would hit the case. Looks as if there is room. but you can't see down around the bottom. It's very close.
I think our bikes with 5 gears is perfect. I used to wish for a 6th gear out on the highway, but what would it really do for us? Maybe drop the revs by 300-400 rpms & 75mph? It's not worth it. In 5th gear @ 50 mph I'm @ 3000 rpm. (In these bikes thats on the verge of lugging the motor (bad) If you had a 6th gear & shifted into it you'd be lugging the motor @ say 2500-2600rpm. That would do damage to the motor over time. I hope HD never adds a 6th gear.
