Remember When Yamaha WRs Were 2 Stroke Trail Bikes

Recommended Posts

Well yes, but I also remember when WRs were Swedish Husqvarnas and then Italian Husqvarnas. :coolio:

66.4mm x 72mm = 249cc........nice thought is that the industry standard....OK KTM standard for its 300s is 72x72, so to make a 300 version of the YZ that fits into the 72x72 mold a simple rebore and plating job is needed. no need to play with the stroke.

Yup. Had a WR400 for a bit. Also had an '83 IT490....before the WR switchover.

Had an IT490 also, Then a '88 YZ250 followed by a couple of 2 stroke WR's before moving on to a plethora of WR 4 strokes. That new 2 stroke WR would be enough to get me to jump back over to Yamaha again but I doubt we will see it in the US. Pity.Never was a big Husky fan. Couldn't get the hang of the left side kickstart.
