I (still) want a Supertwin...

[carlosthejack...]

...but where to start?

I want a road legal Supertwin race rep. I'm thinking there's two ways into it: a road legal ER650 or SV650 and then changing/adding bodywork to make it legal but race looking, or taking an already race specced bike and adding wiring/lighting/mirrors to return it to roadworthiness. Which is the easier option and where the hell do I start?

You just want it to look like a super twin? Or are you getting stuck into all the stuff that makes it a super twin - changing the front end, tuning the knackers off it etc?

[Howling TerrorOutOfOffice]

Big twin yes. Normal 650 twin no. 99bhp 650 supertwin maybe.

depends if you want the hassle of wiring or tuning tbh,

normal road bike = lots of time and money tuning

super twin = lots of time playing with wiring (if its not still there)

edit: sv650 would make a great base bike if you go that route

A race tuned engine and competition box and clutch will be very little fun on the road.

Why?.. Is my first question.

For racing there are good reasons to choose a class like this - it's probably less competitive than minitwins while allowing more freedom to play - you can get them much lighter for a start.

The body work is a bit of a weird thing - on my minitwin I have 675 fairings. So don't see this has got much to do with a supertwin specifically, where you can also use any bodywork.

A supertwin will attract a premium for all the modifications done to it to get the best out of the regulations.
Yet you could get, say, a Ducati 749 and have a pretty similar spec bike that would be more use, possibly more reliable, look more complete and generally be less hassle probably for more money.

It seems rather weird getting a tuned and tweaked smaller bike done to get the most out of specific regulations if you don't have to comply with them and can just use a more appropriate bike to start with.

I'll start again. I want a road bike that looks and sounds like one of the Supertwins I've seen this week at the NW200.

Any easier?

Modding a road bike would be miles easier than the reverse.

I'm watching the Supertwins race at the NW, and I'm still wanting to do this.

Just to clarify - road going twin that sounds like Satan is coming and looks like a race bike. Mightn't even need lights on the front, could make do with a daylight MOT.

How easy would putting clip-ons on an ER6f and then getting the whole thing sprayed up or wrapped be?

This looks like it might be a place to start!

If you feel that strongly about it, just take a big cheque to JHS racing, purveyors of all things supertwin.

I think it is not a bad idea just forget about tuning much- it will be more ocstly than it is worth and you'd be better off getting a more powerful bike to start with BUT-

If you were to get an SV or ER6, put clip ons, race bodywork and maybe usd forks from gsx-r/zx-6r, then you'd have a cheap to buy, much cheaper to insure, sportsbike looking, and riding but for the power. With a race pipe on it would still sound great, near enough to the howl to which you refer.

One question worth asking is what is the fairings the professionals use? The kawasaki one looks particularly 'factory' OEM.

I know someone who has done something sort of the same but used an Yamaha YZR500 fairing and rs seat- will try to get pic posted. He didn't even bother with USD forks but essentially put bodywork, exhaust and clipons on a standard sv (nb will need top yoke too). His insurance didn't change from the standard bike.

Good luck mate.

I'm currently looking into race prepping an ER-6n so let me know how you get on.

I've found some useful bits here:

https://www.twinshack.co.uk/prods/pc11.html

No idea where to get a Farqhuar-esque fairing though, JHS Racing only seem to specialise in SV650s. Although I heard his comes from a GPZ500.

[G]

If you stick a post up on motorforum, I'm sure someone can help you on the fairing.

[Suntan Sid]

Have a look at the June edition of "Ride" magazine, it tells you how and what Mr Farquhar does to the ER6, to get it to race spec and how you can mod your own!
