you guys see that haaybusa in his pics with the ice tires... 500lbs on the ice with a lot of torque... better be big spikes to hold that thing down... i htink id prefer the Gsxr600 for the ice.
But looks cool as hell, i htink it would be a blast to go do, but trip to sweden and cost of it and 340 euros per wreck... i think i cna go ride in tahoe this winter and wreck alot cheaper....lol and do it on one tank of gas round trip.
no chains... that is a cage so when it runs u over after u fall off it doesnt spike u to death..lol
I dont knoiw bout the weight the spikes are all the traction from the sound of it so in a corner seems like weight would cause the spikes to crack the ice around em and make it break loose... straight line maybe weight would help...
but like it says u get more notice of slippage with ice thne asphault so a lighter bike seems like youd feel it break more then a heavy bike where u feel less road. Either way it seems fun and id do it but not a chance in hell of affording it anytime soon.
