250 production class rules?

[Aeromo]

Can anyone tell me why the 250 production class is limited to two cylinders?

Can anyone tell me why the 250 production class is limited to two cylinders?

because there not been 4 cylinder 250 bikes officially imported into NZ in a long time (if ever), so determining what 'production' was on JDM spec 4 cylinder bikes where no english manuals were made was just too hard,

also there were a shit load of Ninja 250's and Hyosung 250 twins being sold at the time the rules where brought in, making it the perfect bikes to make a series out of,

I had thought that the single cylinder bikes (CBR250) were eligible also, but perhaps not?
On paper they might be competitive due to lower weight, but in reality that is unlikely.

Here are the rules , you know , just in case you need to read them

1 and 2 cylinders keeps the field pretty even, but not so even that 1 cylinder bikes would have a chance, even the Hyo's couldn't cut it with the ninjas

This has led to an almost one model class which is pretty good to watch and probably good for the sport , 125's are probably better but that's another discussion

4 cylinder 250s would clean up with good riders , can always ride them in clubmans.

Even development class wont take 4clylinedr 250s

Sweet, thanks for that, makes sense.
Were development rules changed a few years back? as I bought a MC22 about 8 months ago and the lady said she raced it in development 2012. Now I see it is also limited to two cylinder.
What is clubmans?

[steveyb]

250cc 4 cylinder bikes were/are allowed to enter at Vic Club events in their own class, unless the numbers are now low so that the class is off the menu. (I think that is the case). I am not sure that is the case for other clubs, but you would need to ask. I would think that you can enter it in clubmans class at any club.

Does anyone use the trusty ol' VTR250s in the twins class? Cheap enough if they're crashed and easy to cheat with and make moar powah
I imagine the Spada is not allowed now, because it's 40hp, but so was the twin disk GPZ/X250. The Spada was never NZDM either, and I doubt the twin disk GPZ/X was.

the GPX250 was legal, but not sure about the twin disc ones, they are a bit lighter than the newer ninja 250 but the 18" rear wheel made tyre choice harder

GPX was 16" front and rear.

Could make an interesting bike in the class then? You could run sport demons on it \, or Birdgies. Would go quite well.
Especially compared to the whale Hyosungs, mine touched fairings down on the road with pilot powers on it

Are sport Demons any good?

They're adequate for a smaller bike with shit suspension and they come in pretty much any size

I remember suggesting the GPX as a bike to run in the class when I had one a few years ago. People said it would be too slow. From what I hear they have better top end the new ninjas but that could be bs. I think ground clearance would be an issue with the pegs as I remember them being rather low. Sadly the bike got stolen before I got a chance to take it on track.

I've ridden a twin disk and it had a little more pull than the newer ones, it'd be bloody cheap to get and run one though. Which is what I'm all about

VMCC still have the miniLite class (catering for 4cylinder 250). Due to low numbers last couple of years - VMCC are considering removing club championship status, but still allowing them in the development class...
