Opinions Honda NSR 125 1989

@terry-tz Maybe at the fly, I very much doubt that sort of power at the wheel. A tuned Aprilia is around 25 at the wheel.
-
@terry-tz I don't know much about the NSR. Scrim gives me no reason to doubt him, I just know they raced the RS in GP and produced GP versions of the RS and that's the sorts of power they get.
-
A fit full power foxeye nsr 125 is good for around 115mph, my 03 crm has 85 on clock and goes off with ease, just derestricted full arrow pipe.
-
I doubt very much a foxeye nsr will do 115, the earlier jc20 has more aggressive porting and wont do that. They did do a sp version of both jc20 and jc22. Jc20sp had kick start, longer 1st gear, arrow exhaust and a different rear shock and were supposed to be over 30bhp

@calum not too sure whether it actually makes much difference but I owned a 2007 rs125 full power model, standard pipe and carb settings according to the previous owner but with the cdi copper wire cut (supposed to unleash 33bhp??) I had an indicated GPS top speed of 105mph.

@mitch_350z The 2007 models are widely different handling characteristics to the older ones. Revised frame, subframe, forks, wheels and ignition.
They won't be 33bhp, but they'll be the closest thing you'll get to them out the factory.
PJME have a tuned 140cc Aprilia RS 125 on the dyno on YouTube that made 25 bhp, the stock cylinder made closer to 26 with small power band.
But that was at the wheel. Impressive figures for a 125 road going bike nevertheless.

Now I'm turning my interest towards an 1997 NSR. Everything works, 24000 km on the clock and in good condition. Worth £700?
It's fully derestricted. -
@scrimsmustang What do you reckon?
-
Same mechanically, some tend to be restricted in funny ways depending what country they originate from. Physically smaller than the jc20, easier to work on though as the fuel tank hinges up.
@dtr-nsr allright. Will probably pick it up this weekend.
-
I picked this 2000 model Foxeye RR up the other week, never took it flat out but it seemed pretty quick and pulled well for a 125, I sold it 5 mins after getting it out of the van for 1500 quid as is but I liked it. If I was looking for a 125 road bike i would have one now worries, it started 1st push of the button everytime and was a quality engineered bike but its a Honda so you kind of expect it. The bike is now in Tony Armes Motorcycles in Hartlepool for sale if anyone is looking for one, that who I sold it to.

Ive got a well i should say had a pristine 2001 KMX with a stock motor making 19 at the rear wheel on the dyno just with jetting Boyessens and a Giannelli and people say they are slow.

@scrimsmustang A pipe can make a big difference, especially if the stock system is restricted. Good figures though. I had a mate who had a 1999 KMX and he couldn't keep up with my bog standard DTRE (green and black wire earthed), and I wouldn't call the RE a quick bike.
