Overview

How do you make the world’s fastest 2 wheel drive off-road buggy and World Champion better? You turn the expert design staff at Team Losi loose with no limits. Team Losi’s new XXX-BK2 raises the bar for two-wheel drive off-road racing. Starting with the most dominant electric buggy of the 21st century, the Team Losi development team used existing as well as revised and totally new components for a new chassis that allows you to stay one step ahead of the competition.

The key elements of this new design are a new transmission and suspension package that compliment each other and enhance both tune ability and performance. In general, the mass of the transmission and motor has been lowered and moved forward closer the center of gravity for greater forward traction. The increased traction generated has allowed the development of a more aggressive suspension package that offers unmatched tuning opportunities.

The new XXX “Gen II” transmission features a smaller differential with new outdrives, Kevlar® spur gear, machined motor plate, polycarbonate gear cover, revised molded motor guard, but retains the race proven double-disk slipper. Although the diff uses some existing parts, the outdrives have been revised for improved friction dynamics for added traction and performance.

The innovative suspension package features Variable Length Arms, a totally new concept in off-road racing. These new arms feature additional pivot pin, shock, and sway bar locations. In conjunction with the new front carriers and rear hubs, it is easy to alter the handling characteristics of the car to meet the demands of the wide variety of track conditions seen around the world. This also allows the racer to tune the driving feel of the car to better suit his style. To make all this fit into the existing XXX platform there is a new molded forward pivot mount and rear pivot plate as well as a machined aluminum rear pivot mount.

Beside the stunning technical advancements there is also a host of new performance parts like Titanium Nitride hinge pins, o-ringed aluminum shock adjusters, and new shorter CVD’s. Looks haven’t been forgotten either as there is also a new body and wing with most of the aluminum parts finished in Team Losi’s trademark hard anodizing. This remarkable kit allows you to build and tune an off-road buggy that accelerates quicker, brakes straighter, goes through bumps faster, and carve turns with greater speed and stability. When asked what it did differently Brian Kinwald the “BK” in BK2 said, "Dude, it’s just easy to drive a lot faster".
