I never did motorcycle ice racing. And you? I guess Tobias Guckel and Sepp Schmidt from TGS Motorcycles in Germany know something about it. This ultra light custom (try to count the number of frame holes) is based on a rigid frame with single sided front end, oil in frame, and is powered by a 93” S&S Shovelhead engine and a 6-speed transmission! (Do they race very long icy German highways?). For traction, the tires are from Metzeler in 18 x 4.5” in front and 18 x 5.5” in rear equipped with Ice-Speedway-Spikes. “Ice Racer” is equipped with a double chain drive, and a twist clutch for fast shifting. I guess more for indoor shows (how many miles of carpet they already destroyed?) than for ice. TGS Motorcycles.
