The Multi might be stable at 150, but the engine will still be at 8500rpm. Not very practical for either bike. The gearing on both bikes makes sustained speeds above 100mph impractical. I guess you could put a tiny rear sprocket on the Multi...
I had no problems with sustained 95 - 100 mph pace in the Utah desert. Top speed on the trip was getting it up to 135mph somewhere on 50 in Nevada which still felt rock solid, albeit not a safe speed to sustain.
