Trials Australia Forums

Does anyone know....
Looking at ads for jack fields demo show and the all say 'modified' trials bike.
Modified how, and for what exactly??
Cheers!

Yes I know:
1 leaner main jet
New sticker kit
shortened rear guard
Cad spokes, for landing from great heights onto concrete floors 50 times a day.

That's it!

I see...
thanks for that!

Didn't think the bikes looked much different!!
