1M1 barrel ,piston and head


Recommended Posts

Hi everyone I have a barrel, piston and head off a 1M1.

I know its off a dt250 but was wondering what the difference was between the 1M1 and the 1R7 engine.

It is a spare so I am going to put on ebay once i am sure what bike its off.

When researched it says its off a dt250f 1979.

The 1R7 it says is off a dt250 1977-1980, hence the confusion.

Thanks in advance for any helpful info.

Hi a quick update, apparently the 1R7 is european/UK spec and 1M1 is US spec.

Next question are they inter changeable?

Unless someone has specific information (having swapped, or tried to swap one), your best bet is to contact Yamaha.


Or... Failing that, I tend to go on Fowlers and look at the part number for the two items. If the numbers are the same, it's the same item, if not, then it's probably not going to be a straight swap (if at all).
