Vegas and Mojo's are even worse than maxxis.. You can get 2 - 3(at a push) meetings out of those slicks at some tracks.. but if you want to be at the top then you just get a set every meeting :|.. Which I can't afford..
Ha. Try $300-400 USD per set for my race bike. Yeah, you can do 2-3 weekends on them, but after 2 I notice a drastic reduction in grip. And my bike is known for being easy on tires.
