Really would like to see a vid of the building of this bike. Dreamed of building a CZ trials bike back in the 60s, but I was just 14. Thanks.....

[@avdwio]

I heard only wizards can wield the power of a CZ

[@mjlyam]

[@mjlyam]

Nice riding Tim. 👍 One thing though, I wouldn't call this Extreme Trials this is regular Moto trials. 👍 I'm saving up to get a beta 300 really want to start the Moto. practicing on the push bike right now

[@timlewis5527]

Best of luck with trials it's a great sport. As for whether or not this is extreme enough, i think you should re-evaluate your comment after you start riding and especially after you try a pre65 bike

[@trialsrider1952]

I know where I can get what is left of a CZ trials bike.

[@mjlyam]

hi again. what is the front end off ? doesn't look standard cz. thanks for any help. mike

[@timlewis5527]

mjlyam they are CZ motorcross forks but the standard forks work just as well. To make the standard forks rigid enough you have to sleeve the part of the fork (between the triple clamps) with a tube of ID equal to the forks UD. Recesses in the triple clamps house the end of these tubes and hold the front end square.

How much does it weight? I've always dreamed about converting one of the common CZ ot JAWA models to look like their motocross or six days trial models.

[@timlewis5527]

It weighs just under 90kg. So about 20kg more than a modern trials bike and about 30kg less than the standard bike.

[@KamenKachev]

@@timlewis5527 wow you shaved a lot from it!

[@timlewis5527]

Future videos will be in HD

[@trialsrider1952]

Did all the CZ trials bikes have skinny tanks?

[@timlewis5527]

Nope, this tank is a custom fibreglass tank. The original was a bulbous steel thing. It looked okay but was too wide and too heavy for this bike.

[@mjlyam]

this is what I want to build........any tips?? cheers, Mike

[@timlewis5527]

mjlyam hi, the bike is a CZ Trials bike. It isnt heavily modified except the larger rear sprocket, modern bars, alloy wheels, aftermarket shocks and the custom seat and tank. The engine frame and forks are all standard CZ parts. If you have more qs pm me.
