slow bike

[minime_51]

i have an nsr 125 rk from 1990, and is pretty slow, max speed about 70 -75 at a push. it accelerates ok but im jut a bit confused coz i cant find any restrictors. any thoughts appreciated

Not meaning to be too rude, but how heavy are you?


Weight has a big effect on small bikes like the NSR, I have a friend who won't mind me saying is HUGE, Jon rides a GSXR400 and cannot get anything like the top speed that my boyfriend (with the same model bike) can get.

If you aren't particularly heavy then maybe look at other things more technical.... /me looks at Keith/Kev/G/MrL etc.

Has the gearing been changed? If its been down geared for more acceleration then you will lose top end.
Otherwise, it could be the piston needs changing(like mine).

Mines done at least 35000. Its showing 28 but i havnt had a speedo/odo for 18 months!

Test the compression(ask keith nicely), if iots down then it needs a new un! Mines showing 105PSi, lower service limit is 114 and optimum is 142!

It should indeed be every 10k. Official Honda piston/rings kit is £37.50 from Andys in stoke and they always have them in stock. Base gasket is also needed at about £3.

It is gettin that way, yeah. I need to go in again tomorra cos the choke cable they gave me is the wrong one. They ordered 2 and only one turned up - he didnt know if itd fit or not so told me to take it and if it didnt fit take it back.

Just checking that this is the faired not the unfaired model?

The unfaired models seem to have different gearing and the engine in alower state of tune.

[Annabella]

The RK is faired GG......

It's the same model I had.

I know, it's the FK that's unfaired. However there's a lot of confusion with these models.... some people even describe the NS125RK as the NSR125RK. I have seen the unfaired models being described as RK before, so just checking it was a faired one.

[Demonic69]

It'll be the same one me and Robby had.
Should do 90-95 really caining it. I couldn't find any restrictors in mine either, I guess they're just slow

thats the NS in the pic, i thought you had an NSR dean?

anyway, 90-95 was the derestricted speed, i never tried to derestrict mine, only had it for 4 months, and it only did 70. though i once did 93 after a big hill.

Mine was red, looked a lot better.

[Demonic69]

That's the NS125RK I beleive.
They didn't do the NSR125 in 1990 AFAIK

yeh thats the NS125RK, mine was a 1990 model too.

the kickstart was a fucker in the wet, how much would it have hurt to put a rubber strip on it for a little grip?

[Demonic69]

Could have cost a few pence FFS!

NSR or NS125R?
I thought the NSR125 started in the early 90's
