Engines Built for Performance

Cheap engine kits are made for tinkering and last about a month. And expensive race-ready bike engines aren't user friendly.

But BBR Tuning Racing Series Engine Kits are made to run fast, last for years, and compatible with nearly any bike under the sun.

Truly the best bike engine ever!
I'm a bike motorized bike builder and have put together engines from Grubee, Stinger, Zeda, Jet, literally almost all of them and this BBR Tuning Stage 3 is EASILY the best one out of all of them. It starts right up every time and has a quick pick up like no other engine. This guy has a balanced crank that allows it to go really fast without any kind of vibration. SMOOOOOTH running engine from low end to top end.
I recommend this engine. PERIOD!
Easy to install, easy to modify. If you want to go fast when you are on a flat out or climbing a hill on black top this is the motor kit for you.
Best kit ever!
The Stage 3 kit I got is so awesome. Build was easy and the engines very easy to work on. Came with lots of upgrades and I'm getting ready to buy two more.
Impressive motor
It's a better quality motor for sure compared to what you buy in amazon or ebay. This is a fun and a very affordable kit for its performance. I assembled and cranked it with no issues. I use this for work everyday and so far so good.

If it's not BBR Tuning, it's not worth it

Because the BBR Tuning 66/80cc Stage 3 Racing Series Engine Kit does what other engines can't.

Speed You Want & the Range You Need

The BBR Tuning Stage 3 bike engine kit's equipped with a high compression head that's able to give this engine 2+ HP with top speeds reaching 25-40 mph. It also comes with a high performance carburetor for optimal airflow for more torque and speed. And they all come together to give you around 100-125 mpg.

That's enough power for riding fast, taking inclines without losing speed, and getting you where you need to go and back on a single tank.

We keep our costs as low as possible while maintaining the highest possible quality. Some charge under $100 for inferior performance, while others offer elite quality at sky high prices for $500+.

Stage 3 build

The only problem I had was with the hardware for the back sprocket so I went to the hardware store and bought some quality bolts and locknuts that solved the problem now I might upgrade to the arch chain tensioner it's a great kit

Stephen Brooks
Absolutely love this bike kit

If you purchase the smaller sprocket and run a 26”wheel you can get close to 40 mph.
The only thing I wish is the gas tank was a little more robust . But all and all I love this kit, the stage 3 is the best I’ve purchased

Great engine.

Was very excited to receive stage 3 BBR tuning racing series engine. Although FedEx dragged tracking number along. Couldnt find in system. Then bam it was delivered.
I had previously purchased BBR tunning F2 thruster expansion muffler. Wrap with titanium header exhaust wrap. Your leg will appreciated it. Instant power. Running 16:1 fuel mix for 300miles before decreasing to 36:1.
I also rejetted carb to a #65. Maybe needs a #70 but not yet.
Haven't windowed poston yet. Not sure I want to. But I do have a reed valve for that if need be.
Very happy with this kit.

I’d give a five star, but this is a gift for Christmas, so it won’t be opened till then.

I am happy with my new motor it is really more than I was expecting. I am looking forward to using it on my new build. It is going to take awhile yet, as I cannot afford much at a time. I will get done after awhile. I can wait. I want it my way or not at all.

It didn’t run upon purchase!! Asked for parts to fix it and got wrong parts! Then got ignored all together when I asked to return it all as it was over four months of nothingness!!

great engine kit! You must enjoy working with engines and be patient enough to know that this is not plug and play. It's a DIY for a reason. The youtube videos were very helpful!

great time to build My grandson is an engineering student and has asked me to buy this for his birthday. Both of us assembled it and had a great time doing it. We found a leak early on but it was resolved by the phone representative we've talked to.

good engine kit It's a good engine. There were some missing items but they immediately shipped it out when I reported it. It's one of the best quality motors I have ridden so far.

worth it I've been building motorized bikes for 5 years now. This engine is a mid level engine for a reasonable price. It's worth the price.

Nice product! All in all, this was a fun project. My kids were having a great time helping me with it. I'm a mechanic and motorized bikes has been keeping me busy and motivated.

I'm impressed! This is a fun and a very affordable kit for its performance. Me and my roommate bought it for a hobby. We had fun figuring out everything and we got it all together and working. We're almost done with break-in period.

THANKS!! I will buy another engine kit from this seller for my next project! My order arrived on time and there were no missing items. I assembled and cranked it with no issues. I use this for work everyday and so far so good. Thank you!

100% recommended!! I recommend this a 100%!!! Be patient enough to troubleshoot if issues arise as it is the way it is. This is a decent build for an engine and I use it everyday for transportation.

Rory Collins

one of the best! It's a better quality motor for sure compared to what you buy in amazon or ebay! The aftermarket upgrades were outstanding! It definitely increased performance when I swapped the stock parts to the upgraded parts. I'll be looking for more upgrades in the future.

Christopher Wilson

AWESOME! This is my first engine from Bikeberry and it did not disappoint! I have purchased from ebay from another company and it sucked so bad. The seller was not responsive. I wasted money on ebay! I'm glad that a friend of mine told me about Bikeberry and I'm happy with the engine kit I purchased. Thank you!!!

So far so good Just ordered all the best parts possible for a motor ready bike and call cs to ask a few ? They were great no problems even resent my email. I like what I see so far can’t wait for these 5 days to go by lol

Haven't installed my mustang racer 66/80cc but is exactly what I was looking for I haven't installed my motor yet but am about to order the BBR Tuning, motor-ready mountable bike with the gas tank built into the frame and all the other ""works""! I'm also going to order some high performance parts here in the very near future from bikeberry. The reason I know this is the perfect motor for me is because it already came with a high performance carborator, spark plug and CDI unit.....all meant for speed!!! Yes I love to go fast and there are tons of upgrades for this motor!! So if you are like a lot of the rest of us adrenaline junkies this is probably the motor for you! So far there is absolutely nothing for me to give a negative comment about my motor or about bikeberry period (hence 5 star review) because of prompt delivery (even around Christmas time!!) and everything was delivered in perfect condition as far as I can see and was received under a week! So so far so good! Just can't wait to get it all together and cruiseing down the street!!
