Yamaha XS650 SP
Japanese locals, An-Bu, built this menace for the 2013 Yokohama Hot Rod Custom Show. The Base model is a Yamaha XS650 however the displacement has been punched out to 750cc. Power was also stepped up in the form of a decked head to increase compression along with a bigger cam. The custom exhaust is full stainless that snakes back to a JET muffler. An Bu says the power is straight monsterous, thus deserving its name.
