BBR Tuning Racing Series Stage 4 66/80cc 2-Stroke Engine Kit

Installation instructions

It is a great product and works fine once you have the drive mechanism installed on the correct side of the front wheel axle. I though it was not working for two weeks, until I thought two switch it too the other side of the wheel. If it had installation instructions with it, I could have avoided the agrivation.

I'm not sure how much it helped to be honest.

I chopped it off at the end to make a non muffled banana pipe. Way more power. Way too noisy now, but I'd rather ppl hear me. It's safer.

Good Carb

My stock carb leaked, this one doesn’t. Be sure to remove the elbow bend before installing the throttle cable or it won’t work.

Don't know ask Ryan!!!!!!!!!

Best Customer Service

Love, love the bike! Watched YouTube for instructions to assemble- especially to attach the back bike rack. BikeBerry was fabulous at keeping me updated on delivery. I highly recommend them as a reliable company with great customer care.

Easy return

I accidentally ordered the wrong item. I called for a return number and was able to return the item.

Fast shipping. Legit site. Had a hard to find got item in stock. 52v 10ah mini battery. Gives me about 10 miles range on my 750w bafang mid drive with lots of throttle use. 👍🏽

Awesome have trouble with mounting studs staying in the vibrations work them loose

Petcock sizing

The petcock they sell doesn’t fit so they had to special order one


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
