"The bike is a Honda CRF450 2006. For a long time I have had the vision on the ultimate street tracker. Ultimate in my mind is one with minimal bodywork, centralized weight, lightweight carbon fibre and a concept motorcycle feel to it. So finally I got around to it and used my Honda CRF, a modern aluminum mx frame, powerful four stroke 450 thumper engine and light weight base." 

"Every modification is done by myself - Welding and modifying of FMF exhaust, welding aluminum sub frame, modeling and shaping bodywork mold base in foam, manufacturing gas tank, belly pan and bodywork in carbon fibre, (hand laid by me), lowering front forks, designing parts in the CAD program NX and then 3D printing them (sprocket cover, axle cover, light bracket etc). Even paint!  The focus on the bodywork has been to make it as minimal as possible and at the same time improve the handling of the bike with for example mass centralized gas tank and exhaust. You can actually look straight down on the valve cover through a hole as nothing is lighter than a hole."

"There is the Fender of Inspiration with people that motivates me! RSD included.

The frame and swing arm is stock but everything else is either modified or simply removed. The aluminum sub frame is the strength carrier for the rider and the mounting piece for the carbon fiber gas tank. On top of it all is the thin sleek carbon fiber body work where every surface of it has been questioned if it is in need or not in order to reduce actual weight and show the true lightweight appearance. Seats are for touring bikes! This is a barely street legal race bike with battery powered lights. Built for short stints on your favorite curvy village roads outside Stockholm. The license plate is a Japanese one I bought many years ago in a Tokyo moped market. It will be replaced with a Swedish one to reduce the traffic cops interests. They will probably have some opinions on the bike anyway. The LED ring that makes the front light has a 3D printed bracket developed by me. The battery is hidden underneath the lower yoke. The covers on front axle are 3D printed and the cover for rear brake caliper is in aluminum. Both added to reduce the fussy and a bit disturbing areas there in a typical concept bike manor."

"The engine is modified with a one-off FMF exhaust system with shortened silencer tucked in underneath the engine but with the header length and MegaBomb intact for best performance. It breaths through a UNI pod foam filter.

Improved performance with Boyesen Factory Racing Clutch Cover and Boyesen Super cooler water pump cover, Robust and stylish red silicone Samco hoses matched to modified larger aluminum aftermarket radiators, Goldentyre 19 inch Flat track tires and for the rear brake a Fasst Co brake spring kit." - Marcus Moto Design
