ProTwin rule clarifications

**GSVR** · 6th April 2008, 10:44

I have just sent an email to MNZ over some information I would like to know and will post the reply here when I get it. Heres the email I sent.

Hello Paul,

I have read the Protwin Rules and are confused over the Subframe rules.

Could you advise me if the rear subframe and undertray have to remain OEM unmodified or is this area free to modify or replace?

Also another matter that I'm unsure of is the use of non standard tyre sizes. There has been some debate on a popular biker website over this and I am considering fitting oversize rear tyres to my bike.

And one last thing is the Homologation of bikes. My 2003 K3 model is not on the list of Homologated bikes nor are any of the earlier carbed models (1999- 2002). Will these bikes be getting added or should I apply for homologation.

As far as the the ProTwin class is concerned I think it is a great thing for the sport and hope to see the class flourish.

Regards and thanks
Garry Hosking
MNZ 16435

I think ProTwins is one of the best things for the sport in a while and want to see it really take off so getting any gray rule areas sorted early is important so we all know whats allowed.

Billy mentioned that that certain twat has appealed MNZ's regection of the protest re. Morgan's rear tyre size i.e. he's still not officially NZ champ. Pretty sad affair really.

All this debate and research - Garry you must be doin' PT nats next year!?

The appeal was withdrawn as I understand it and Karl is the new Protwins Champ

We already do Know! ( it is in the rule book if you want to read it) if you can type english, you must be able to read it, so check out the rule book, you will get the awnser from there easy and fast, as well as save some of Paul's very valuable time, that he donates to us!!!!!!!!

Good joke mate, Paul Stewart IS NOT PAID BY MNZ- He is paid by HONDA NZ
Your questions are all awnsered in the rule book!

all other items not mentioned below must remain standard.......and rear subframe isn't listed......
thats from the rule book......well not the rule book as the rules for protwin came out after the rule book was printed, just on mnz website......confusing eh...

True, the rule is pretty clear i.e. you cant change the rear sub-frame - its been identified as something that should be changed (as established in another thread) and hopefully gets changed for next year.

**johnsv650** · 7th April 2008, 09:12

thats your thoughts other have different ones, is it because one make with more hp needs more advantage over another make........
just leave them standard,

Ah!! but is it that cut and dried?It all depends how you interperet the writing of the rule!!The rule states that fairing brackets and instrument panels may be changed And as I see it the Tailpeice is part of the fairing kit and is held on by the rear subframe(As discussed with Paul Stewart while the Protwins rules were in the experimental stage).Therefore if you cant change the rear subframe you shouldnt be able to change the front either therefore rendering most of the Protwins bikes illegal.The battery box and undertray are as stated at this stage illegal according to the rule book!!No argument.I also fail to see how replacing an aluminium subframe with a steel one gives a bike any advantage.Of course there will be the wankers who will say thats only my opinion as a supplier of these alleged illegal subframes,Think again my Jigs and moulds are well and truly paid for by now and if I dont sell another one who cares.Im busy enough doing 600 and 1000 fairings anyway.One needs to be careful they dont tread on the wrong toes or they might find their own teams equipment under scrutiny at regular intervals

Of course Cooky,$10.00 for the kit and $1000.00 for the DT levy.Whats the DT levy I hear you ask.Well its our newly introduced DORK tax specifically introduced for time wasters

**johnsv650** · 7th April 2008, 12:35

billy,
both main models come out with naked versions, and faired versions, naked ones are allowed to make a front subframe to suit, the rear fairing will fit a sv if you use earlier models, is that correct ? k3 and k4 rear seat will fit onto standard subframe......just use the earlier seat mould !
old stock out the door........simple
sell whatever model fronts and the seat from a k3 or k4....everyone happy
