More and more drivers are getting into 1/8 scale GT touring, and the ROAR-legal O.S. SPEED 21XZ-GT was designed specifically to give those drivers a competitive edge. Based on the SPEED 21XZ-R racing engine, the GT features a new cylinder liner with 5 scavenger ports and 3 exhaust ports, for improved power in the mid- to high range. The crankshaft is also new, designed solely for GT touring, and is silicon-potted and DLC coated with tungsten weights pressed in. The dual adjustable carb also conforms to ROAR regulations, and comes with a 7mm restrictor. The outer head has a lower CG, along with shiny fins.
