250 gp bikes for f3

[scracha]

The proposed rules said that 350 2T MUST use original frame and swing arm, which means RZ350 is tha latest bike you could use. The new rules have no mention of using original frames so repowers of any sort are allowed? There are a few repowered bikes out racing anyway
The rules sort of read as long as it has production cases and a production bike you can fit what ever engine into any frame

Will ask MNZ when it is on there site

Have you got a NSR engine and a RGV ? be a nice combo

Saw a tatty one in the UK. Good handling (the NSR400 is too old), weighed fuck all and reliable and not too peaky 76bhp.

i didn't spot any restrictions on after market fairings or using bodywork that doesn't resemble the original production bike's silouette. Did anyone see anything i might've missed or is it looking like Tyga bodykits (for exmaple) are all good under the new rules?

Narp, looks like thats been dropped, all good to get artistic !

[ahamay]

So, am I totally blind or do these rules mean the 250GP bikes have been given the boot and now have no class to run in?

[satchriossi]

You're not supposed to use them in F3 but as far as i understand, you never were allowed so nowt's changed there. Theyre all good to use in F1 or, more appropriately, F2 where of course Glen Skachill used an NX5 RS250 to win a race a couple of years ago. Clubmans is fine and there's the dude with the TZ250 (you?) running in those races.

COOOL!!!! Which year Billy?

Isin't it amazing how desire or enthusiasm turns one thing into another in people minds.
For some reason some people thought that 250GP bikes had been included into the F3 class (at NZSBK level), and did not understand that it was only a proposal!
That proposal has been quashed and 250GP bikes will not be included in the F3 class at NZSBK level.
On the other hand, what clubs want to do is up to them.

Having said that, it was possible to buy a pretty tricked up Japanese F3 250 proddy bike from Japan back in the day that would be as close as it is possible to make a proddy bike to a 250GP bike. Jarrod Wintle had one at one stage even if it didn't go so well at the time. Maybe some of those are still around?

Also, I have not yet got my head around the rules, but maybe this bike (in 400cc version, not 500cc) will be eligible???
It uses production cases and a production chassis, although from different manufacturers. Check it out!!!
Designed and manufactured in NZ and Australia. Can't do better than that ay?

Err,Not sure,They must be reasonably late model though,They are a copy of a set Leon Haslam used at the Malaysian GP.

Re the multi cylinder 2 stroke rules for F3,Ihave serious doubts they will be ratified by the board in their current format as they are just a step too far,I have seen one of those Aprilia/Banshee engined machines dynoed locally and it was producing in excess of 100 rwhp.Plonk that in an RS or TZ chassis as the current proposed rules allow and youd have a seriously fast F3 machine

Sounds like some sense at last, having a class were kiwis can build and race there own creations is long overdue as there are many talented builders in NZ.

I also think this class will create alot of public interested with all of the different styles of 4 strokes and of course getting some 2 strokes back out there.

Heres my entry...

That is a trick looking NSR bro !!

NICE!! So that's a Suzuki RGV frame and swingarm, NS400R motor, presumably a bespoke exhaust system, Tyga footrests, Ohlins 46HRCL remote resevoir shock but where, or what did the wheels, forks and brakes come from?? The seat cowl looks Tyga shaped but the subtle differences make me wonder if its a one off, self supporting unit?

Well done on the project so far! Not that i'd want to block you from using it for racing but are the miss-matched engine and frame legal for F3? The KR1 dude was straight in there voicing his objection to my 300 kitted NSR before it was all made legal so he's probs not gonna be impressed with your Honzuki if it isnt strictly kosher!

Aren't those NS triples good for making about 70 horsepower at the crank? Have you done anything special with the airboxes? Are there HRC parts that work with that engine at all?

That looks awesome! Keep up the good work.

Will look forward to seeing what comes out of the woodwork in the next year or so with these new rules.

Hey,

Correct on the engine and frame, the forks are FG348's ohlins made for the 07-08 gsxr1000, the front brakes are 290mm Brembo racing cast iron discs made for a late model rs250r, mated to Fireblade calipers and a Nissin Factory 19mm radial m/cyl (off a puka 500GP bike). The front wheel is a magnesuim RS250r rim 3.5x17, the rear is 5.25 Marchesini made for a rs250r 5.25x17.

The engine has been Wobbly tuned with cr125 barrels modified to fit, basically every part of the engine is modified or improved.

The rear seat is self-supporting kevlar/carbon based on the last of the nsr500 tails. Custom made by myself with much help from Dilz and Drew.

Should be up and running this side of xmas.

Cheers

Very impressive!

[satchriossi]

HOLY SHIT. I love the carbon airbox, does it fully seal to the underside of the tank? Will it be fed by a ram air duct? Is the tank carbon/kevlar too?

Have you got some proper exhaust gaskets sussed to stop black jizz running out the headers? Its gonna make a proper mess coming out of the the rear facing cylinder. I use a combination of these metal/fibre gaskets from supercheap auto and Threebond 1207B to make a good seal that lasts and resists virbration.

That front end is pure SEX mate. And it thought sliding an RVF fork into my MC21 was cool...
