Far as it holding the horsepower, that's good to know but am wondering about the wheelbase since the zx10r are already an inch shorter than the other litre bikes (54.5in.). I think I'm going to go ahead with the build.The swing arm will be able to hold any power you need.
It is designed for a liter bike just like the stock swing arm on your zx10 is, so if the stock can take it, the single sided one from the MV will too.
Wheel base shouldnt change much, but check the build thread of the bike with one, i think he had some info on chain length.
Do it, do it!!!
I saw some guy leave u up his number who does machine work but when i called it the number was no longer in service. Is there anyone on here who can machine the part for the dog bone linkage on the swingarm?If you search here, there was a member that has done this already. He recently sold the entire set up/bike, might be easier to find in the classifieds. Be prepared for a lot of machine work.
