Twinshockandy Posted March 2, 2020 Report Share Posted March 2, 2020 Is there anything interchangable between these ? engine covers, shock unit etc Andy Quote Link to comment Share on other sites More sharing options...
jonboy883 Posted March 3, 2020 Report Share Posted March 3, 2020 Pretty much the only interchangeable parts would be the tyres and front mudguard ? They are completely different in engine, gearbox and chassis. 1 Quote Link to comment Share on other sites More sharing options...
rcgods Posted March 3, 2020 Report Share Posted March 3, 2020 Front wheel spindle Front wheel (Pinky) Front brake (Pinky) Forks and yokes sort of interchangeable but need to change the stem to a TY Mono one as the forks are larger diameter Air Filter Probably some other odds and ends too. Mudguard and mudguard brace are different on the TYZ as the forks are different. 1 Quote Link to comment Share on other sites More sharing options...

thai-ty Posted March 4, 2020 Report Share Posted March 4, 2020 So, completely different bottom end? Clutch plates? I was always under the impression the TYZ was pretty much a water cooled top end on a TY Mono bottom end. Even the side cases look similar-ish.... Then again, i've never seen one in the flesh nor had a motor on the bench.... Quote Link to comment Share on other sites More sharing options...

Was wondering that, myself, hence asking the question...............certainly generator cover looks (and here I'm like thai-ty having never seen a TYZ in the flesh) he same, Also was interested that the monoshock unit wouldn't fit, but looking at the swing arm unit on a TYZ (via good ol ebay) I can see they are different.

feetupfun Posted March 4, 2020 Report Share Posted March 4, 2020 The TY250Z motor is based on an early 1990s YZ250 motor. The TY250 air cooled mono motor is based on an early 1980s YZ250 motor. They started with a clean sheet of paper for the TY250Z but did use the pinky front wheel. 1 1 Quote Link to comment Share on other sites More sharing options...
tshock250 Posted March 4, 2020 Report Share Posted March 4, 2020 Pretty sure the 250 mono engine was based on the yz490? Quote Link to comment Share on other sites More sharing options...

The size and weight of the crank would make one think so... the term bulletproof is a perfect fit for the bottom end of this motor. Quote Link to comment Share on other sites More sharing options...
