My V-Strom had Shinko 705 tires at that time. Although they are considered more of an 80/20 tire, and they do fantastic on rainy pavement, they aren’t very good in snow.
I have new tires now. Heidenau K60 “Scouts”, with a knobby 50/50 tread. They actually do very well in snow, but snow is snow and it’s still a slick proposition on a motorcycle regardless of tread.
This past weekend, I rode up the Clackamas River Highway east of Estacada, and turned right across the river up Memaloose Road. It was paved the whole way (except for a quarter-mile stretch of packed gravel), which was kind of a let-down. I wanted to get some more off-road practice. Once I was above 3,400 feet elevation, I started riding through patches of snow with bare lanes of pavement where truck tires go. I came to a junction with NF 4550 and it was covered with snow, and both roads leading away had snow as far as the eye could see.
So I turned around and headed back down toward civilization. On the way, I saw a gravel road going up a steep, rutted hill. I cut a hard right, stood up on the pegs, and climbed the hill. My Heidenau’s worked great and I navigated the ruts and slope with ease. It wasn’t a long climb, maybe 100 yards, so at the top I did a four-point turn and headed back down. Again, the Heidenau’s did a fantastic job of giving me good grip and control.
This off-road stuff is a lot of fun!
