Four stroke options

[mboddy]

Funny how on one thread they're wingeing about franken bikes and on another where building them love it.

Difference is that the other FrankenBikes are historical aberrations, potentially using many major components from much later bikes.

So were there lots of Kawasaki and Suzuki 4 stroke motocross bikes racing back in the day?

[Hoony]

short answer - NO

4 strokes back in the day.
Obviously there were some.
It was certainly possible, if you desired.
During the "Thumpernats" era, there were plenty of 4 stroke MX creations.

Hi fellow VMXers,

I think my next vmx bike will be a four stroke. I.ve had a few XTs back in the day but can't imagine an XT or TT for vmx, as much as I love to see Rob Smith on his thumper. Probably can't find or afford a CCM, so what do you think?
I will never be at the front, so being competitive is not an issue, but handling is important, decent suspension too.

Cheers

The VCM EVO class in Victoria was one this year by Chris Conboy on a sensibly modified XL250S. The bike was plenty fast, reliable and looked easy to ride compared to the various big block 4 strokes that run in the class.

my tt/xt500 donk in a 81 RM full floater was inspired by a Dutch team, for the 4 stroke class in 82, built mine in 83

thank you LWC82PE

the 510 is an easy one, they are about and parts are available with a lot of carry over to the later water cooled bikes.. even easier is to slot a (pick fave jap500 etc) into a 83 husky frame. 13 inches of plusho travel and plenty of room for that boat anchor engine...

EVO550 - what is the rear guard on that please?

Stilmotor made them as well

There's a can Am Sonic on Bikepoint. That will set you apart from the herd.

Does VCM run 2T mx bikes in Evo?

[bigk]

Yes Ted they do, EVO is for all, no differential between 2 of 4 stroke for the class.

Im thinking of building a 4 stroke bike from stuff I have lying around here,an IT175 roller,just have to find a front wheel and an XT250 engine,not evo legal but Im sure it will be a fun bike.We mostly ride natural terrain on my mates property 2-3 times a week so no rules out there.
Anyone tried a 4T in an IT chassis?

[Nathan S]

Fitting a taller 4T motor will be difficult in any IT175 frame, which all have the shock over the top of the motor.
Also, most models have the chain on the RHS, to add to the hassle.

[James Lee]

good point Nathan,drive is on the wrong side,shows how much Ive looked into it.
