Hi everyone,
I have a 1990 NS125R fully faired, and derestricted with a full DEP pipe.

I have managed to get 120mph out of it, has anyone else managed this?? I don't know how this bike is so fast!!

Please reply and tell me what speeds youve had out of your NS125R or NSR125 or NSR125F.

Cheers,
boyceyyz250

I find that very hard to believe I'm afraid.

Sorry!

Not necessarily, it will be an indicated 120, closer to 105 MPH, which is quite possible for that type of bike.

Between me and my friends, we had just about every 125 sports bike, the fastest I've seen is 115. I was on my KR1S and my mate was on his Gilera 125, his speedo read just under 120, mine showed 115, and he said he was at red line.

Another mate with an NSR125 got 110 at redline. 125's 'really' struggle over 100.

Yeah, someone was on the other day and said they had seen 120 on the speedo, was really closer to the ton.

This was about 10 years ago! Very Happy

On par with the Cagiva Mito / Aprillia AF1 etc.... pretty quick 125's.

could be bolocks cause my mate has a SV650 restricted to 33bhp and gets it to 110 tops.

Weight disadvantage/bulk-less aerodynamic/more to push through the air with a similar power output.

I had a TZR 125, slightly over sized piston, Carbon reeds, jets, Arrow pipe or something etc etc.
It sounded like it was going to blow up at 90mph and that was ragging it.

I’ve heard my VFR will do 130 maybe more, can the NSR really do 120mph!!?!?

Hi

Not a hope that an NS will do 120mph. Flat level ground and fully derestricted it would manage a bit over a true 90mph. The speedos on them were well know for over reading. They are a mid to late 80s designed 125, and not the quickest when new. The original Aprilia AF1 would take them happily and that had a road test top speed of 94mph.

I have managed 115mph on level ground out of my RS125. Indicated. Reality probably 105mph or so.

All the best

Keith

Ive had this disscussion once before, And we had a qucik test to prove it. I konw a lad who kept bragging that his aprillia rs125 went to 120+mph, so I though if this was the case then surely it would beat my 33bhp VFR400 NC30?? So onto the motorway we hop. he's going flat out behind the screen making my ears bleed with the stupidly loud exhaust can he had on there. arrow i think?. anyway he was going flat out almost on the redline with me along side him at 105mph still pulling. I went past him upto 110mph and slowly went away into the distance.

I had an indicated 105mph on a 2000 model NSR125. Only did it once, mind.
