I got 21,000 miles out of my chain for a 06 1krr. Is this normal wear or should it have lasted longer? I do oil it every 3 to 5 hundred miles and check for wear. Since Im going to change it here soon, do I need to swap out with new sprokets?
Thanks for your help!

 

If you keep it well mantained (every 500 miles) then it can last for 30K miles or so (on a 525 which is stock). a 520 chain on a 1krr will last around 8-12K miles if you keep it lubed (from what i heard). But yes i would do a whole new set (chain+sprockets) if you like, you can always drop a tooth in the front and add 1 or 2 in the back for more acceleration. from what i heard, alot of people love the -1,+2 or even just -1,0.

 

Vermino is spot on, however chain life depends a lot on how you ride also. A lot of drag racing, or wheelies/stunting type of riding is gonna shorten it quite a bit.

 

on the 04 1k I thought the stock chain was 530? what happens if you go from a 525 to 530?

 

WHOOT what did i win?!?!?

on 04-05's they are 530, but 06-07's are 525s..

going from a 525 to a 530 is just like adding about apound of rotating mass on the motor, which will make the bike more sluggish but more dependable (less likely the chain needs to be changed).
Usually only stunters use 530+ because they put a constant abuse on the chain (yet most stuntersare using 600cc's anyways, so it's not like a liter bike's power). Track bike are usually 520's so they keep the rotation mass as low as possible (every pound counts on the track)

i say 520's are good for 600cc (last around 12-16K miles) where liter bikes (last around 8-12K miles) so if your just a weekend warrior and ok with forking out $300 or so every 8-12Kmiles- go for it. but i would be going thru alot of chains [8D]

 

ok good cause I have 04 and I just change my chain and sprokets not too long ago and used a 530 -1 front +2 in the back of course .

 

THanks for the info! Now if I go with the -1 +2 in the back, will I see a bigdrop in gas milage? I mostly use my bike for commuting and taking long road trips on the weekends.

 

Didn't affect my mileage at all I still get the same.

 

haak30: quick note

the stock gears on 04 is 16 front 41 rear. I think the rear on the 06 is 42 but not sure so i'm not sure if it will make a difference on yours since it will be at 44 on the rear with the +2.

 

^^ correct

-1,+2 drops the max MPH from 186 to 150 (or so) redline*. But if you shift like normal (at 5-7K rpm's) it wont affect MPG.

*dont hold me to that, just from what i've heard
