For those that want speed

[Al.Fisherman]

While searching I ran across this cz 516 125c. Kinda expensive, but for those that want speed....here you go. Sort of on the heavy side weighing in at 59# A little less then 3X the weight of a HT. Zoooooooooom

those are what they used (or used to use) on short track speedway bikes.

When I followed motocross, I was a CZ fanatic.Their engines look artistic and really haul the post. My Honda S90 needs an engine. Hmmmmm...

its a bleedin good price if its NOS! and look at the rated bhp compared to the ht... if ht had that power to weight ratio...oh boy!

iunno if you could get one into an s90... i wanted to stuff a cb250 into my c90 a factory blueprinted cb250 with 5 extra horsies annoying thing with the c90 and 110's is they have a different mount to the 50 n 70... same with the s90/s110 models? not sure... and all chinese engines, even the 160s, have the 50/70 mounts... luckily i have a c50 awaiting restoooorations


but owwww! that jawa! soooo...tempting!...must!!!!cut!!!up!!!!cred!!!!it!!!!card!!!!


when you think of what a speedway bike actually IS.... a pushy isnt really that different...just take off the brakes and chuck a bungee cord on the forks!


would love to fab a pipe up for it!
