2 strokes rule, sorry but its true.
Faster
Look better
Handle better
Brake better
Accelerate better.
Light weight
But yes they are old and yes they need some care. Only the RGV has very very silly power valves but, the NSR's are fine and work better.
The 250 4 stokes are a more sensible bike, sensible like a flat cap, pipe and volvo. Nice if you like that sort of thing but........
Saying that once you get to 400cc's 4 strokes are cool again. Take off the cap, chuck the pipe and set fire to the volvo then chuck it off a cliff. Finally bury it upside down with a stake through the sump. All at a crossroads.

They handel worse, the powerband and the high center of gravity make them handel worse.
brake better? they have no engine braking so they cant brake as well?

**Fluffy Cat** · 30th April 2006, 21:20

Texmo, your words give you away.
You need a 2 stroke and quick....medic!.
They brake quicker because they weigh less, sort of a physics thing i belive.
RGV has a little sort of power band but not much and the NSR's power valves, god bless mr honda. Work so well as to leave you wondering whats a powerband?.
Have you looked at any moto gp bikes, they moved away from low c of g's a while back(think elf and Ron Haslam), now a higher c of g helps turning with flick in. Have you sat on an NSR i would'nt describe it as a tall bike. Kind of minature.
Get a 2 stroke before they are all dead and gone. Or get a volvo sorry meant to say 4 stroke 250, keep getting them mixed up, sorry.

And Crash it and write it off

I don't know, but the 4 stroke 250's aren't that slow. I was racing at Taupo today in Formula 3 on my CBR250, and I came 7th out of 12 in F3, beating an RGV 250 in all 3 races... However it should be noted that the guy who won all 3 races was also on an RGV 250. However it should also be noted that he spends about $5k per season to keep it racing. He was lapping about 3 seconds per lap faster than me. But it's his home track, and he's spent heaps of time there, and it was my first ever race there.

- also happens on CBR's but not as much (they ride too slow to use brakes much anyway :P) and most other bikes with slightly thinner discs (250's usually).

Learnt that one the hard way, geniune front disc rotors are $600 a piece from japan

(And you have to buy 2, ouch).

I picked up some locally laser-cut ones from a guy in waihi beach for $300 a piece (& $225 for the back disc). Was an expensive learning exercise, (though the font discs were down to 4.1mm and needed replacing soon anyway).

Other than that in the six months I've owned mine I have only had to replace a cosmetic piece of tubing, rear tyre, chain & sprockets. The ZXR is especially good if you of "larger" build.

Vtec a good, very good effort.
Just think on a preped NSR 250 you could have made a few places, maybe top 3, you also need a 2 stroke or a 400cc 4 stroke.
Be a devil get a 2 stroke, that RGV you took was a sissy and needs to get back to the 2 stroke brotherhood HQ for some counselling.

**Ixion** · 30th April 2006, 22:09

A two stroke with valves is like a chick with a dick. Very good thing. In the wrong place.

**vtec** · 30th April 2006, 22:49

Haha, so an RGV with powervalves is like a female to male trans-sexual then?

Thanks fluffycat, but I think I'll stick with four strokes. Can't stand the idea of having to rejet them for every race. And even though rebuilds are easy, I find the more times you take something apart and put it back together seems to age things a lot... Bolt head get slightly rounder, threads get slightly weaker. The bike just gets older every time you strip it and rebuild it.

Go the ZXR

The 2/ 250s go for considerably less than the 4/ ones. With the exception of super tricked out race-rep NSRs, which go for as much as or more than the 4 strokes.

Expect to pay ~$3K for a good NSR or RGV. ~$5K for a CBR RR or ZXR.

Ok, firstly....if I sell my car...I can get one of said bikes above.

That's the whole point.
Secondly, I didn't say I couldn't afford it, I just can't afford to have both the car AND a bike....so the car goes, the bikes enters.
And 3rd, I've been trawling Trademe, bikepoint, biketrader etc etc. for about the last 4 weeks and it would seem that I can get a ZXR or CBR, both from '89 up to about '93 models, for prices ranging in between $2300-$4500. They may not be in mint condition, but scarred fairings are nothing, and having something to work on suits me fine. I'm mechanically minded, and workin' on your bike I reckon is part of tha appeal and culture. (Within reason of course) I'm sure as shit not spending $5k plus on the same machine at a bike shop that I can get on a private sale for $2k less....even if I do have to put a new chain on myself, or do some other minor work.

But thanks for your input.

Cheers,

...it seems that this thread is gradually turning into a "mine's bigger than yours" thread.

So thanks to all the people who've given unbiased, technical, useful, thought provoking info to a newbie who needed help.

I think I've made my mind up on what I'm after...just have to wait for the right combination to come along.
Catch ya's in another thread.

Yeah, but...

NSRs have two cylinders to worry about, two carbs and are easy to rebuild.
4-strokes have 4 cylinders 4 carbs 16 valves timing chain/gears and are horrendous to rebuild.

I got on my NSR after a brief and painfull experience on a sj125 scooter. I thought it was easy enough to ride, even if I did shit myself (5 times the power will do that

) occasionally.

And 2-strokes make you feel a little bit "special" IMHO
