Title: DT175 pistons.
Post by: Nathan S on May 29, 2008, 06:48:08 pm

I've confused myself...

Can anyone tell me the bore and stroke of the 1985 ~ 2006 DT175? This is the one with the rectangular headlight and the safety seat.

OK... So the fact that the RT180 has a different BxS means nothing?

Not sure what you mean Nathan???
Rt 180 has 64.5 by 54 dimensions.

Somewhere between 1979 and 1985, Yamaha changed the piston, rod, head and barrel in the DT175.
Until last nighty, I had been of the belief that they changed to the RT180's 64.5x54 dimensions (remembering that all of the info I have is US-sourced, so doesn't include the later DT175s).
