For this build, we went to our old reliable: a big-bore kit on a Honda CRF250R makes it way more fun to ride, and adding Twisted Development to the mix can make it even better. Also, the Vortex ignition (mapped by Jamie at Twisted) allows the bike to rev with the big-bore. A big-bore alone in most 250Fs can add 2 to 4 horsepower, and Twisted’s mods and mapping can boost that to 7 or even 9, so it’s quite significant when ripping it around the track.
