450 Super Singles

[Coyote]

in all the 450 single stuff I have seen in magazines or on the net the idea is that you use your MX bike frame, motor and swingarm. Strap on another front end and a shorter shock, staple on some bodywork (RS125 comes to mind) and go racing.

I want one:

a) because I like singles ; and

b) I think it would be a blast; and

c) don't they just sound fantastic?

Awesome cause that's the way I'd do it due to cost. Thinking of doing it to an XR650. Preferably in a way that could be reverted back to a Motard or Dirtbike. Looks like the bikes in the video have road bike chassis though. Not sure what the Kawasaki is but the Suzuki looks like an RGV and the Honda looks like an RS250

A big single in a lightweight chassis would make a great road special, a modern take on the cafe racer concept of tritons and tribsa's.
But for racing, big singles are already catered for by super motard or for that matter classics.
Why stop at a 450 when 600+cc gives more stomp.
The sound of a big single with an open pipe, nice...

Lyndon from Boyd Motorcycles in Hamilton runs a CRF450 converted to a super single in Formula 3. Don't know if he's done anything to the motor but you can see the thing pull a good 10m gap on anyone coming out of a corner. Sticks like dog shit. It was quick enough for him to pull 3rd/4th's all day long at club level.

Just got to see the video. Now I see they were using road bike chassis. I was thinking of bikes like the modded Aprilia SXV550 that was on KB a while back that was a motard with RSV forks and shock and with road bike fairings.

These bikes look awesome. Only problem is there is hardly any motors around and the best way is to buy a dirt bike and swap the motors around. You get a super single and a very quick (top speed) dirt bike

GAH!


the idea is that you can buy a stock dirtbike brand new for $13k, slap on a front end from a sportbike, lower the rear a bit to match, get a set of rims and then slap on some fairings. all up a brand new racebike for under 20K, and the bikes both already conform to engine/emission standards from the MX comps and will create a fun new class for people to race in without having to buy a dodgy bike from the early 90's from an overpriced road market

Well sweet then, that's way better than I thought. Could've sworn by the looks of them they were like road bikes, especially the Suzuki.

Reckon an XR650 would be good for it then? Something I don't have to rebuild so often. Plus I've got a VFR400 swingarm that could go on it so I'd have a nice 150 section tyre on the rear. Unless that's too fat.

Here's the Aprilia I mentioned: http://aprilianews.blogspot.com/2007...ek-rsx550.html
