my newly acquired 2005 ttr is geared fine for the road, 75mph + but it seems very tall on the trails,current sprockets are 14/44, I would like to try the 14/52 combo that seems to be a good compromise, but the more I read about it the more confused I'm getting, what size chain would I need?, taking into acco...

Trying to swap out the kouba lowering link for the original length. I've taken the plastic caps off the swing arm to remove the 17mm bolts and sleeve. Trouble is, the bolt and sleeve just spin around. I can see the sleeve has two flat edges, but obviously whatever surface was holding is still has been kna...

Hi Everyone I had a bit of a problem............... Fitted a new mt43 on my bike, the gearing was 13/50 which I quite liked, not to much loss on the road and very good in the lanes. Well I could not get the 520 chain tight enough unless it was on the very last setting on the snail, so no room for tightening when...

Fed up with the chain rattling against the Case Saver, but not wanting to lose that bit of protection: I changed from 14/50(3.57:1) to 13/46(3.53:1), there's no noticeable difference in the overall ratio, the bike rides just the same, but, thankfully, the rattle has gone. Incidentally, 14/50 need...

Hey everyone, I've got 13/48 gearing on my bike. I've just bought a second set of rims to run my 50/50 tyres on and thought I might go a 46 rear sprocket. Anyone know if the chain set for 13/48 will still fit with a rear 46. Chain adjusters are on 8.2 currently. Can't remember how many links. I'm prett...

Hello everyone my TTR has currently a 13/44 set up which I dont like. It feels far to tall and I don't seem to have a lot of low down power? i was thinking of going 14/50? Would this give me more low down drive?

Padowan · Padowan

I know there's been a few threads on chain/sprocket combinations, but I though I'd start a thread from my experiences that gives a few sprocket, links, tyre and adjuster combinations and what sort of clearances they give at correct chain tension. Maybe this can build up over time into a referenc...

Notice the one link has a flat pin, like it was grinded down. This is not the master link, there is another one just like it, so there are atleast two pins like this. The chain feels and looks completely fine in every other aspect. thank you
