Gear Backlash on the R3R

[Gaolbird]

2011 Rocket Roadster

Has anyone ever heard a dealer talk about Gear Backlash in the transmission. When I roll on the throttle in 5th gear at 120kph pulling 2800-2900rpms there is a notiable clunking sound that is felt in the foot pegs. This clunking will go away once the rpms creep above 3200-3500rpms. The dealer relayed some info from triumph saying that the R3R uses straight cut gears and with an engine this size gear backlash is common. The guy working on my bike took it for a ride and he thought is was a broken ujoint, he rides a R3 Classic and he has never had that happen on his he said.

Anyone else experience this?

Sounds like a problem to me, but I'm no expert wrench. Whatever it is it is definitely not normal.

Post this up on either or both the general tech Talk or Common Issues forums and I guarantee you'll have a good idea of what's up right quick!!! Good luck.

Nope, mine don't do that and neither does the wifes.
of course both of ours are standards, so maybe the gears are cut different...

Can anyone confirm the story about the gears being cut different on a Roadster than other Rocket models.

I have 3500 miles on my 2011 Roadster and have not experienced that problem. Good Luck......hope its an easy fix.

I have had the same problem but it seems as if it is slowly going away. A friend of mine called it "clutch clug" which is common with shaft drive motorcycles. I have never owned a shaft drive so I'm a rookie to them. I have over 5k on it now. When I feel it starting I just ease off a tad and it will quit.... once up in RPM it totally goes away. I just keep riding hoping I don't have to use my extended warranty.

Doesn't happen on my 2010. Can't help you with the gear cut question.

Sounds to me like the torsional damper. The final drive is the same as is the internals across all models. Ride it until it blows.

You remember talking about that on the other forum awhile back?
