Old Dirt bikes as basis for projects

Post by neale » Fri May 11, 2012 10:55 pm

OK, this is probably a stupid question, but they're the ones that usually help some of us learn.

Been thinking about what I'd like to try to get started, and something small and tidy is what floats my boat, (and preferably single, all my bikes have been singles or V twins, current ones being an XV1000 & Pegaso 650 single, never could cotton on to the sewing machine acoustics for a bike) an SR500 would be nice, but looking at what money basket case SR500s are going for sorta stopped that idea, so widening the net a little I was looking at the '70's 4 stroke thumper dirt bikes, and from what I can see, something like an XT500 should make a fairly nice starting point, from what I was looking at, possibly even better than an SR500 (head angle etc), and they're available for a lot less money than "nice" bikes that more people want.

So, is there something obvious I'm missing here, or would the old thumper dirt bikes work as a starting point for a chopper project?

Thanks,

Neale

I reckon you will get some enthusiastic responses on this one.

I agree that an older trail bike of reasonable size is a good start. You have the fork length already and ths small tank and small headlkight and tail light... Being high off the ground, they can easily be lowered by rake and dropping the back end plus sticking in a 5x16 rear tyre... and you are well on your way.

Also frames are failrly simple, single top tube and minimal bracketry etc.

You can bolt in the xr 600/ft 500 motor into a cb250rs with minimal fuss along with the ft front end wheels also fit the brakes as well, cb250rs do make a nice little cafe racer if i can find my past project photos i will try and scan/post them.
Ft 500 motors can be hard to find as they are ugly and about as wanted as a red headed stepson and the motors usually end up in buggies because of the lecky start.If you find a cb250rs with lecky start that will be an import -model not released in Oz.

Thanks guys, and yes, I was expecting enthusiastic (negative) responses, too ;^)

NB: Yeah, a 16" rear was part of the thinking on this.

Using a Thumper is not a good idea.

XT/TT 500 are exxy cos they're great bike. Big money when restored and popular with the VMX crowd. There are many sub-genre's of motorcycling enthused with these bikes.

FT500 engines very popular with the Supermono racing crowd.

XR Honda's are bulletproof, but exxy cos they're still going strong.

You might find a DR 600 or 650 cheap.

Well I MAY have the basis for my first project, have to see what state it's in and what I can do with it, picked up this '86 XT600Z today.

Look forward to seeing the results... just taking off the tank cutting off the rear of the frame and dropping it will transform it for starters!

I think the first steps will be to get it running and possibly regoed, Hopefully alterations done after that won 't be scrutinised as closely in the annual pink slip checks?

Interesting, someone recently put up pics of "wrong" XTs, and some of them weren't too far from what I'd like to do.

Hopefully the engineering needed will be just for the hardtail etc and therefore possibly almost affordable, providing I can get it running OK it may actually end up as a "proper" chop.

FWIW.
