This is an NXA, the last customer version HRC made before discontinuing the RS250 line. I don't know if anyone in NZ even has one of these ones. RS cycles has one crated still for $27,000US i seem to remember if anyone's keen?

Anthony Mcarthy has an NXA 250 in his shed in Christchurch Jay lawerence rode it a couple of years ago.
Attached is a dyno Graph of my own NX5 250 on Av gas Anthony's NXA on 98 unleaded and my 450 as Glen Rode it last year. Remember the 450 is 50-60kgs heavier than the 250's.
Now which bike would you Choose???

Well, that makes it bloody easy..... Holy cow! Impressive plots...
Still, I guess you still have to be able to ride one.
I guess this lady may be able to teach me a thing or two...

[Mishy]

I'd take 83hp with that curve !
that was always a pretty good engine - good enough to win 250 GP races at National level even on a bad day, and with a fatty on board.
It's still basically not far from a stock, out of the crate model. A kitted bike of some sort would just make our one look stupid.

As i said in an earlier post:

It s a " no brainer" , these words fit well with the one suggesting the concept.

So its agreed that the 250s are way ahead of any production based bike.... funny that - so what can we do about it??

do we complain to MNZ ??

i actually don't mind the proddy 2 smokers going to 350 not a bad plan at all -

You club rep what is going to the MNZ meeting to vote on it.

So ignoring the GP bikes,
An RGV taken to 300 apparently pull 70, . . . while the crank & gearbox last. Hard to take them any further. That should make them sort of competitive. The only 350 is the poor old RZ & it will pull 70hp if tuned right, but need a decent chassis or all for naught. VS a top handling modern bike with more kilos but a wide spread of more power.

They would need free reign on chassis.

Yeah the 350 limit to an RGV i think is fine - it would be more on the lines of the INTENT of F3 - production based bikes that are formulated or modifying for racing....it also matches the 650cc lines more as a 300 -350 2 smoke is closer to a 650 4 stroke ( as close as a road based one will ever be ) a 250cc road bike had very little chance against a 650.....


My VJ23 - RGV250 had 65RWHP was quite hot but never lasted a race.... 70 would be achieveable for sure. You get a hot NSR with some nice wheels and some good tuning and you would have some good fun. I've seen An aprrilia Rs250 ( older one ) at 73hp with arrow pipes and some good old porting....


A GP bike just doesn't fit f3 - If the 250 GP riders got together and went to nationals - they could get there class back. how many would there be in the country?? it would be a nice steup up FROM F3!!

Wrong!!Make an informed and sensible submission too MNZ and the roadrace commission will consider it,

M y old VJ22 (ex Grant Ramage/Suzuki NZ) produced 72 rwhp,Stage 1 ignition,Sagaya pipes,Robert Taylor porting and a few other mods including boring the carbs too 35mm and raising the port timing.A 350 tuned properly should produce around 80 rwhp,But it wouldnt be cheap to build by any stretch

[F5 Dave]

As far as I'm aware they (RGV) don't go out past 300 easily. By 350 are you meaning RZ?

I know where there is one of these for sale in the South Island if anyone wants one. It is a minter!
Also, My 2000 RS250 model was putting out about 78hp STD, so that appears to run inline with what mr McCarthy's one puts out. I sold mine to a guy in Washington USA, cos noone over here wanted it! Man I forgot how cool these look, also they are probably the easiest bikes in the world to work on, honestly everything about them is so nice!

oh, FYI, Mr Beck had 2 TZ 250's, one here and a higher spec on in Japan. He ran his one here through a flying quarter just before he sold it and it did 264kph, my 2004 CBR600 did 262.

I would be getting a 250....

[Whitebait]

For sale: Nice 3 bedroom house in Wanganui.....................HHAHAHAHAHAHAHHAHAHA

P.s Rossi do you wanna buy a share in that NXA??

[Billy]

Nope,Built an RGV350 in 05 but never bothered to develop it as there was no class for it outside of supersport

Assuming your talking about the commission member that put the idea of 250gp machinery in F3,You should also know that person wanted the rules relaxed around the air intakes of the 650s and was denied

I wouldn't mind knowing how much the owner wants for it even though its bound to be way more than i can afford... These seem to be fetching mega money whenever they come up for sale. I'm hoping that once the Irish ban them from their road racing championships a load of NX5s and NXAs will come up for sale relatively cheapish. *Fingers crossed*.

Thanks for the graphs Ozzy, those are some strong motors!
