Chain & Sprocket

Hi all,

I have a 929 rear wheel ready to fit to match the front end I fitted to my 98 RRW earlier this year and before I order a new rear sprocket I just need to get it right in my head.

From what I can find out RRW is a 525 chain, 108 links, sprockets 16/43. Sprocket carrier has a four bolt mount.

929 is a 530 chain, 108 links, 16/43. Sprocket carrier has a 6 bolt mount.

So, if I've got it right I need a 43 tooth 525 pitch sprocket with a six bolt mount to suit the 929 sprocket carrier.

Any recommendations as to where I can get one made, only found a couple of places but must admit I haven't looked too hard yet.

Thanks

do renthal not do a 520 race conversion for the 929 , i now they do one for the rrw , that would solve the problem but mean you would have to change your chain as well , hope this helps

Hi Stephen
Thanks for the reply. I had thought about the 520 conversion but not sure what the benefits are, apart from the lighter weight. Might just get in touch with a few places and see what they say.

try b&c they might now someone who does bespoke one offs , i have had one done but it was bout 10 years ago and cant remember who did it

B&C do make sprockets you require.

Cheaper option is to convert your 525 to a 530 pitch in which you'll find cheaper to buy on ebay. Mr Honda went for the 525 size to play the power to weight game by reducing the weight by 3lbs. Since then they went back to the 530 on all their current bikes. This would give you more mileage whilst the 520 is for racing much harder stress rate and more expensive.

got to say i always go down the road of the 520 conversion just habit i think but for road use you have to buy a quality chain coz the cheaper options stretch like elastic ive had one snap not that long ago and take out part of my crankcase

Thanks for that suggestion MB. I see the 92-95 and 00-03 are all 530, only the 96-99 are 525. The 530 front sprockets for those years all have the same part No, would that also fit my RRW, ie same spline on output shaft?

Yes they do fit Mick, changed Chimpys 525 pitch to a 530 as these were cheaper and will get more mileage. Also found the very expensive chains were so hard which hardly needing adjustment tightened up with high spots when worn whilst the cheaper versions you adjusted the chain more frequently when worn stretches more evenly across the 108 links with less high spots.

Thanks for the advice MB.

A full kit on eBay is only 80 quid delivered. Looks like the way to go.

Cheers

Done the same to mine, as i have a vfr750 sssa in the back ( which runs 530 chain). I need to replace the chain as i've fitted the worn one (that came with the vfr arm) temporarily so i can line the arm in the frame,

Does 108 links = 216 rivets? Reason, i don't know how many links the vfr has as standard and don't want to buy the wrong length

16/45 sprockets fitted, so i thought if i count the rivets and half the number that should be how many links i need.

Sorry to waffle on Mick, didn't mean to hijack your thread!

Did you have any stress fitting the 929 wheel? I understand it's the same as a 954 wheel but the 954 has a few grams of weight removed at the hub, and the 1000rr wheels are the same but lighter again.

Be interested if you can weigh any bits while you have them to hand. Bathroom scales or I weigh stuff like that with a digital luggage scale!

Might look nice with a 3-spoke 190 in there

Clive,

No probs mate. there's always somebody with the answers to these little problems, best to check before parting with any cash.

A Morti,

The wheel's just about fitted into an Aprilia swing arm, went in without much fuss, but just need the last few bits before I'm ready to fit the arm. I knew the 1000RR wheels were a bit lighter but they were three times the price I paid. Can't weigh the wheel now as 190 tyre already mounted.

doin the rsv swingarm conversion myself think im goin to try and get a rsv rearwheel to simplifiy the mod there 5 spoke so it wont look to differant to the honda wheel
