Fireblade 1998 RRW rear sprocket

Hi to all,I'm still new to this forum and would appreciate your help.

my RRW needs a new chain and sprockets. The ones I have at the moment are standard: 16 teeth front and 42 teeth rear, the chain is a 525 HV produced by DID.

1. What does the HV mean? Cannot find any info on the net. I'm fine with the 525. Should I really bother about the HV???

2. Was thinking of replacing the rear sprocket with 2 more teeth (44 teeth instead of 42) to have a bit more acceleration. Grip on maltese roads, unfortunately is already horrible so cannot increase it more. Do I need to have a longer chain? More links? Have read somewhere in this forum that changing that reducing the teeth on the front will increase the stress on the chain?

3. Would i be able to buy a complete set or should I go for individual items?

I looked into final drive kits by DID, Renthal, Tsubaki and JT. They all seem fine to me. The bike is used mainly in weekends with no track use...so i would say not abused at all. Any suggestions would be greatly appreciated.

Thanks. Bernard

HV is the model or quality of chain.
D.I.D. Racing Chains & DirtStar® Rims
HV is not listed but I think it's the OEM chain so it's quite likely fifteen years old now.
I would suggest getting the highest quality you can afford.
If you're replacing the sprockets as well I would switch from 525 to either 530 or 520, 525 is a fairly uncommon size nowadays.
I recommend going one tooth less on the front sprocket, if you find you want more than that then you can add two on the rear sprocket without having to change the length of the chain.
Yes, theoretically you would expect more wear on a smaller sprocket, but for all practical purposes any difference is negligable. Older bikes run 14-tooth or even smaller so modern 15 and 16 tooth sprockets are already pretty big.
Entirely up to you, sometimes chain and sprocket kits are cheaper and have the chain already cut to the required length, although you still need a riveter to join it anyway, which also does the job of cutting it to length so it's not that big an advantage having it cut to length.

Re: Fireblade 1998 RRW rear sprocket

Thanks Bladeracer.

I will then get the 520 sprockets on their own, the 520 with 15 teeth/42. This should still be fine with a standard length chain.

I was thinking of going for the 520ZVM-X or the 520VX-2.
I will be buying a riverter tool as well and was thinking of this:

I'm running the VX2 on my ZX6R and '90 GSXR750 currently and I think it comes with a clip link rather than riveted?
Yep, that's similar to the the chain tool I prefer. Be sure to grind the rivets off before trying to press the pins out.
