That is on the pricey side.

Also the victoria motorcycle club uses a kr150 for its scholarship thing.
Dont hesitate to buy one,

I've already figured it out cheers, the "F" model came with mags, different expansion chamber and some other goodies... sounds like my sorta deal but time will tell... clutch is slipping in the car so that gets the $$$ first

Worldwide, there are apparently 15 models of KR 150! But in nZ I'm only aware of 3. The 98's are the wire wheel ones. In good nick and well jetted there are nearly as quick as a similarly good RG. The handling is VERY primitive and the 18 inch rear is a pain in the butt. However a good bike to start with if you're just 13 and only 35kg. We had a tiny little girl start and with a modified (we took most of the foam out) seat the KR was the only bike she could possibly fit. Then ther's the 2001 model. Still an 18" rear, but mag wheels and the later generation motor. These are called "race replica" " cyclone" models I think. There are a few about and they are a rocket. One of these won the Sports Fotoz Cup this year and no RG could get near it in a straight line. Dodgy handling tho. then the KRR. They still make these and the handling is brilliant but power is about equivalent or a bit less than the RG
The Aprilia has fantastic handling but is slow,(it makes sense being down 25 cc's to the 150's.) A good CBR 150 in bucket trim is quicker. Big chubby tyres look good but slow it down too. And DON'T blow one up, the parts prices are horrendous. And in road spec they do not like going straight to the track. The engine WILL blow up. They need heaps more oil and main bearings changed to C4 clearance. (So it's technically illegal then of course)

Ok, thanks for that information... umm yeah, unfortunately im not 13 and only 35kg, more like double that weight and 19yrs old... oh and 6'3"....

But i'll have a looksee and like with any bike, see if any of those on my watchlist fit me well enough and then go from there

Daniel Mettam. He's the man!

I will be stoked if I can keep up with him round Taupo but sadly the best I can hope for is for his bike not to be working on the day....

**quallman1234** · 22nd December 2009, 08:50

What did you buy Max? Are you racing your "Streetstocker" or whatever it may be at taupo?

Daniel is about that size, he's not a bad little rider. No fear.

KR150 is nasty. You will have to be super competitive.
WAAAAAYYYY back in 98 when both models 'started' the lineup, not a single KR150 got in the top 10 on the track. Some guys modded to keep up with the RG's.
The RG is almost a stock race motor and needs very minor tweeks to deliver real world performance. However this said they are like mobile hand grenades and you never know when they will die. The KR was always more reliable.

Yep, I had the KR150F (cyclone race replica model) when I bought it it had 25,000k's on the clock (4 years old) and it had only had the rings changed during that time. I put another 50,000 k's on it and only had to change the spark plug a few times before I sold it still working sweet as.

I have lost count of the amount of times my RG has required a rebuild...

Well I dont know what you people are doing that would make your RGs so unreliable,I raced mine for 18 months without doing more than gearing ,tyre changing and a general checkover between meetings.Maintenance is king with a racebike.Identify the problem areas and check them regularly,Dont wait for something too go wrong and then blame the bike
