No if you look at the pics on the listing it states that they are all SP400/SP250 machines

ah right, i was just going by what ive seen in the hrc manuals.

The rules must have allowed those parts then? I dont see why they wouldnt after all the NC29 SP400 kit had a kit gearbox, kit rads etc

So were kit engine parts allowed in SP400? surely they wouldnt show the pistons, rods etc if they were just standard kit

No no kit engine internals apart from gearboxes as far as I can tell. Thos NC30 & NC23 pistons look stock to me

The oil cooler is part of the ss/sp kit Rhory (radiators also).

There's no exhaust listed in the ss/sp kit manual, but I imagine they would be allowed to change it for this class, most (all?) street based race classes that I know of have been able to. Maybe it mentions this allowance in the manual text?

oops......erm...it's been a while since i looked at the manual.

I was just searching through these forums, looking for stuff on the TT-F3 bikes. Hoping this is the best thread to dig up info.

I used to have an MC21, it looks like Honda dominated this level of racing and there's just a wealth of killer race parts and bikes to draw inspiration from for your own bike. I just picked up the Suzuki GK76a, and I was wondering if these were even raced successfully in the series, maybe even kit parts exist? Seemed like a weird move from Suzuki to go to the double-cradle design again, when most of the winners are the typical twin spar frame stuff, even considering the previous version of the bike was too. Curious to see if other bikes as well 3tj FZRs, KR1s, etc. Most of what I can dig up without being able to read Japanese is all Honda V4/MC21, or ZXR400, and a few RGVs.

There's a pic of a yamaha F3 bike in this thread: viewtopic.php?f=35&t=13845

I'm pretty sure Suzuki campaigned some GK76a's in the 1990 season (and probably after too). I know Polen (the reigning champion) picked up a really bad injury in the 1990 pre-season and didnt compete in many races that year before moving to Ducati.

I'll try to find some pics.
