What's great about the BBR Tuning Stage 2 Bicycle Engine Kit is that while it gives you increased power and speed, it gives you a smoother and more consistent ride than ever. Utilizing the Stage 1 engine's low heat and high compression, the upgraded Stage 2 will also give you unprecedented spark and even better breathing ability.
Quality Engines with Top Quality Performance
BBR Tuning is known for producing engines that put out high performance and never disappoint. With a BBR Tuning 66/80cc Bicycle Engine as a base, you'll get superior quality and performance over other engines on the market. Add the BBR Tuning High Compression Head on top and you've got a dependable engine that runs cooler, harder, and faster than anything you've seen.
This Filter Will Give Your Motor the Air It's Been Waiting For
With the upgraded BBR Tuning Speed Carburetor Air Filter you'll turn your stock NT carburetor into a speed carb in two seconds. Just unbolt the stock filter, slide this on to the carb in its place, clamp it down, and once you start your motor up you'll feel the difference. This air filter will let your motor take in more air, letting it run a little cooler while also giving you a little more speed.

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 manufacturers 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 equal 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.

The engine is awesome. Great top end like advertised. Very fast and I’m 220ibs and I’ve easily hit 40 mph on a straight. Of course I have my bike set up for speed as well but this engine is just perfect for what I need. Thought I did not get a Mount for the air filter and had to use the basic one that came along with the package
Unpacked everything and all parts were there. 2 of the four acorn nuts stripped out all the threads and other hardware was needed to complete the build. Include torque specs next time
Was packed great looks good and rums good
Super fun. Great motor. Had to do slite modifications on the bike but turned out great ��
A few minor problem's,the CDI took 2 weeks longer than the rest of kit to arrive.And had issue with the 4 bolts holding the top end to bottom end together. Working through them with Bike Berry help. Will use them again
