“The solid mounted XS race engines create a vibration so extreme, they actually make the bike a challenge to handle, and in the end will rob you of speed through cornering and straight acceleration. And all the while, you’re losing feeling in your hands going down the track.”
“This problem only gets worse when the XS engines are modified to create more horsepower which of course equals more vibrations. So much so, it’s very common for XS engines to literally shake the bike apart, even through your lock wire and gallons of Loctite.”
