This cool XS400 tracker by Drewpy screams “look at me”. The bike has been a popular topic of discussion in the XS400 community and custom bike scene over the last several weeks, and is soon to be featured in The Horse magazine! There are many modifications Drew incorporated into the bike that are not immediately apparent. No part was left untouched in creating this bike. Some of the features include a gas flowed head, cut down 2 into 1 exhaust, clutch window, hidden master cylinder, and the list goes on and on. It’s all the more cool as it's street legal too (well barely) and can been heard, and then seen, tearing through the streets of Rainy City, Manchester UK.

See the build pictures and how-to’s in the forum. Also check out Drew's blog. Great work Drew!

Welcome to XS400.com. We just acquired this domain and intend to create a sister site to XS650.com. This site will have a similar look and feel as XS650.com except that it will be dedicated to the Yamaha XS400. Many people post on XS650.com regarding their XS400's so we thought it would be a great idea to have a site dedicated to the Yamaha XS400 fans. It's going to take a couple of weeks to get this site up and running, so for now, check out www.xs650.com
