Unicorn has 42 or 43 teeth at rear depending on the generation...

Can I go for the unicorn's 40T???

Thank u so much dude..

well, it might be a slight loss, but we don't have too many choices when it comes to overgearing p180...

Or you can check out my "World of sprockets" thread and choose a suitable 40T .428 sprocket... tell me before buying so that I can confirm something if needed....

The ug4's perfmnc los?

Karizma's 40 teeth is on .520 chain, although it might fit. But then you will have to change all of it, chain, front sprocket because everything has to be on .520 then...
And biggest problem is that Karizma's front 13 teeth won't fit P180 UG3... That's confirmed by someone.

If you're thinking .520 pitch, then go for P180 UG4's kit...

Thanks for the reply dude...

mine's open.. as am running on michenlin 120/90.
wil d ug4 kit loose on perfmnc.. then i think it wud betr to find a 40T... wil d karizmas suit. n be a gud option.
hw is los experiencd in ug4.. is it an overall loss or is it in acceleration.. if itz realy noticeabl then am nt going fr tat kit..

Better remove the chain guard after replacing the set... So that weight difference can be substituted to a small extent.

Also, p180 ug4's chain is specialized for open covers, I think its O-ring.

P180 UG4's kit will fit, but it will make it heavier. I have heard of people doing this, and losing on performance. Although, it may or may not fit directly...

But since we don't have too many choices, you can go for it.
