Awesome service from BBR super happy with the product and quality, would definitely buy from them again!

Solid upgrade for the 140, not any crazy power gains but a noticeable difference, I got the performance cam and 26mm carb with mine. Would highly recommend the carb.

Great idea 1" Forsner bit makes a perfect hole. Great air flow in my klx 140.

yup

Parts have been a very good quality and always seem to be packaged well. It makes the rebuild process smooth.

Perfect fit! The extra height for me at 5’ 7” is nice. No more stiff knees!

Big upgrade Improvement to the bike helps strengthen and improve the frame structure also giving protection to the engine will be purchased in another one for our other bike

Big bore kit worked as it should, BBR forgot to send the gaskets with the kit but when I called they 2 day air shipped them. Good kit overall.

Great design really ties the frame together. Much more than a normal SP..
Dual function really, nice job

Came with a ton of stickers which I love and the jets work great on their big bore kit would recommend 10/10

The CRF150F feels stronger over the entire RPM range.

Very well built …..bolted up nicely except for a little interference with exhaust pipe

GOOD QUALITY OF PRODUCT

Ordered several products from BBR. All were of good quality and were delivered in a very reasonable time frame. So far happy with BBR overall.

This is my 3rd build with BBR products. All BBR products fit and perform with excellent reliability whether your playbike riding or racing. It’s all about customer service no matter what you but, and BBR is the best.
