The DR350R (both of them) we raced has a rear disk brake.
What was scary, was racing (trying to, anyway) them before I had the
suspension modified. That bike slapped my head on the ground twice in
the first six miles I raced it. Laying on the ground, I almost cried;
thinking of how it was a brand new bike that Deb had bought for me for
Father's Day. I knew I was stuck with it, and it would probably kill
me if this was what I had to look forward to.
$500 to Scotts Performance was equal to a whole new bike in terms of
predictability and racing ability. I could now push it to the edge.
I basically left the engine alone (air box cut-outs only), and if I
wanted to go faster, just didn't back off the throttle.
I think, considering your climate, that the Shell Rotella Synthetic
5w40 ($15/gallon at WalMart) would probably give you the best
compromise of low viscosity in cold weather and protection when it
gets warmed to operating temp.
If you don't mind waiting for the engine to warm thoroughly in cold
weather, I would go with Shell Rotella 15w40 ($8/gallon) or Mobil1
15w50 ($?).
