What about something like this for the next project.. F5 bikes...



Interesting KTM quite like the look of the oval spars

Nice to see my new F3 GPR frame (GPR009) fits a FXR
(seems as I'm not allowed to race my 250 TZR/GPR in F3/superlight, even though 400cc specials are

Why not????

[Yow Ling]

Why not????

I think the frame needs to be production based, so RS250 is OK GPR is not so OK

5 Specifications for up to 400cc two stroke production based machines:
The machine must be based on a production motorcycle. No homologation is necessary however the Road Race Commission or Technical Steward shall have the power to rule whether or not a machine is eligible.

l wonder what is considered production based for a one man band ? l remembered benelli motorcycles only needed 3 bikes to race in super bikes. was given 2-3 years to get 10 bikes a year made.

What an utterly ridiculous rule.
So who's going to bore and stroke a 2006 Honda RS250 to 400cc

[crazy man]

think the aprilia rs250 is fine but so i,v been told the sp frame is the same as the race frame. but insaying that the honda no matter how look at it, its still a production bike. you would think they would support more home made stuff

Its a shame, i do note that it appears you have started numbering the frames though Scott (first PIC)
In the Mini MX at least you can apply to the mnz for Holomogation based on 10 bikes.

No just a production frame not the engine; no you can build up a old RZ with very expensive aftermarket big bore kits and/or find a quad engine and put it into a RS250 production frame; But you can't do the old fashion Kiwi thing and build your own frame and slot in a +20 year old 250cc road production motor brought for $20...
But you can slot in a stinky heavy 4 stroke 650 into a one off special frame... Rules damn...

The entire build (not including Crazy man's time) would have only added up to < $2k (RS125 Forks, wheels, rear end, fairing + controls, ignitech, pipes and pistons).
but it is built and can be used in other forms and parts can be used in other projects...

yip; thats the catch. based on a production motorcycle...

All the bikes have been numbered. but not sure if that would wash as each frame has a different intended purpose/engine/size etc.
but given there might be 10 frames by the end of the year...

Not sure whom would give a two hoots anyway (I have been told to turn up with it at club level; likely as I suck and would only be making up numbers).. someone has to come last.
It was more of a diversion from where the other conversation was going,,,,

But isn't the GPR frame based on the RS125 NX4 frame? That is a production frame isn't it? One could use the arguement that your frame is based on the RS125 frame which is a production frame and therefore fits the (dumb) rule.

following on from the rediscovery of the dude from midnight oil.
this guy's been seen peddling "mountain man" oysters and it maybe why bro was checking his the other day.

You can put an up to 500cc two stroke single into it....Flettner got enough bits for another Bighorn motor ?

As an aside I've built 13 Aermacchi replca frames now - maybe I should apply for homologation....lol.

[crazy man]

bye everyone thanks for your good info . l should of lisen to jason ..

[Bert]

bye everyone thanks for your good info . l should of listened to jason ..

Well its been a few months away from posting (mainly due to life sh!t getting in the way and crazyman getting chased off the KB forum)...

Anyway; the GPR workshop has been humming. And seems as I'm now back from overseas; I thought I'd post up a few photos.

Crazyman has finished his new GPR150-008 2013(and had a play at the last wellington round).



The Sister bike is my new toy another GPR150-009 2013
Some would say I've seen the light; I say I'm temporarily blinded by actually finishing a days racing without a headache...
The TZR100 has gone under the bench until I can figure out what to do with the slipped sleeve.
This also allows me to build up my 250 track toy to play with Crazyman's SXV550...



So; should see you all shortly and roll on summer.

[mr bucketracer]

puts order in . i want a britton front end with a 25000 rpm engine twin thank you

Send me a pic of the Stud spacing on the TZR Brent i might have something to suit here.....
but I am guessing your sleeve wasn't shouldered then?

Come on it only KB Scott wasn't chased off was he? he just got in an argument with Robert .. Doubt he was the first that's done that.
I am guessing they were both fueled up on ethanol as well....
