Don't waste your money. Ran one today on my 05 Hayabusa, extended 8 inches, brock pipe, power commander and lowered.
1st run Spun through and part way through second gear
2nd run a little better spun through and hooked in second gear
3rd run spun half way through first gear
4th run lowered air pressure from 12 to 8 psi still spinning to tree.
5th, 6th, 7th, 8th, 9th runs all spinning off the line and to the tree.
Tire slipped on the wheel about 4 inches each run. Track was good and I did not change my launch but lost .1 on 60 ft times and over .2 at 1/8 mile.
Tire is round profile like a road race tire, not the flat tread that they have shown in their proto type pictures and will not get a good wide contact patch even with low air pressure.
In short I have already ordered another MT MCR2 and will take the Metzler off when it arrives. For the money and drag racing the
Metzler SUCKS.
