DT175 pistons.
« 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?

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).
