The BBR Tuning 2-Stroke 66/80cc Bullet Train Electric Start Engine Kit is an ideal upgrade for experienced builders ready for more speed and a higher level of performance.
Please note: Sprocket Clamp Assemblies included with Bullet Train 66/80cc, BBR Tuning 2-Stroke 48cc and 66/80cc, and 4-Stroke 49cc bike engine kits come with only 1x set of metal plates. Older production of these assemblies included 2x sets, but from testing and redesigning, existing engine kits and engine kits in the future will only require 1x set. This redesigned assembly helps secure your rear wheel sprocket better than in previous production.
Also note: Due to the design of this engine, most parts (including cylinders, pistons, cranks, and gaskets) and performance upgrade parts (including upgraded mufflers, carburetors, cylinder heads, and case covers) do not fit on this engine. DO NOT purchase parts or performance upgrades designed for non-electric start 2-stroke bicycle engine kits

Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of "80cc", the true displacement of the bicycle engine is 66cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 80cc, therefore we have listed them in the same way on our website. However, the bore and stroke of an 80cc being 47x38mm equals 66cc. Therefore the true displacement of the 80cc bike motor is 66cc. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However,in the east the displacement of an engine includes the area of the cylinder head's combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all "80cc" engine kits on the market today are actually 66cc in displacement size if measuring by US standards.
