Take the winning heritage of the 21XZ-R, combine it with the 21XZ-B's superb features and what do you get? The Speed R2101: a top choice for 1/8 scale on-road!
Its specially designed 7+3 port cylinder liner ensures stress-free acceleration, great power at maximum rpm and improved fuel economy. The DLC coated crankshaft has tungsten weights and is potted with silicone. The crankcase is a new design that provides efficient fuel flow from intake to exhaust.
Sporting laser-etched Speed Tuned graphics, the Speed R2101's machined head results in improved cooling and a lower center-of-gravity. Finally, a black-anodized carburetor makes it possible to run with richer fuel mixtures.
