Earle’s Kit Turns Ducati’s Monster Into a Carbon Fiber Flat Tracker

Originally penned more than half-a-decade-ago by noted custom motorcycle outfit, Earle Motors, the II Mostro is a carbon fiber-bodied flat tracker based on ’90s 900cc Ducati Monster. The project is the brainchild of Alex Earle, who spent more than 2.5 years as a designer for Porsche, before accepting his current role as Design Program manager for Volkswagen America. The car-designer-by-day began the project with a 1:5th scale model, before 3D-scanning the little bike and using that data to produce the molds for the bespoke, carbon monocoque bodywork.

The immense success and hype garnered by the tracker — including the release of a HotWheels version — prompted Earle Motors to release II Mostro as a street-legal kit that can be grafted onto any ’94-’99 900cc Monster. The transformation not only raises the seat height up to 33” (from about 30″) and completely rearranges the riding position, but Earle also managed to shave off more than 80lbs — with it now tipping the scales at 345lbs — putting on par with your average beginner-focused quarter-liter single. Other highlight on the kit include Motogadget electronics, 19” RSD machined tracker wheels shod in Maxxis DTR-1 rubber, fork guards, a Nirrox saddle, LED lighting throughout, K&N filtration, Vortex bars held via custom risers, Ducati Performance rear-sets, a heavily-revised chassis, a custom-tuned bespoke exhaust system, and a four-bolt body attachment setup.
