Today we added two new twins to our website. The first is the Shreadhead Edition 45cc. Shreadhead has done a lot of testing with the twins for us. With his twin he shot for keeping the front end on the ground for quick take off and insane top speed. Being that it is the smallest displacement we offer the torque is less aggresive than the bigger sizes. Also being smaller it is the highest reving twin that we build. Video of the 45cc twin can be found in this blog post http://www.oneillbrothers.com/blog/promovideo/ (skip to 4 minutes for twin footage)

The second new twin to go up is the 57cc. Same bottom end as the smaller twins but with Zenoah 36mm top ends to get the displacement up. Being the biggest twin we offer the 57cc has proven to have the most torque out of all the sizes.
