BBR TuningBillet Springer Chain Tensioners

Used a motor fromOnline. Possibly Korean. Mechanic I went to couldn’t tell. However. After this chain tensioner the motor performed flawlessly. Ok. A centrifugal clutch will make it bombproof. For a 13 yomIt’s close to perfect. Son is ecstatic with the bike and engine. Love to watch him ride the roads at 25mph with a helmet and pads and a smile

Waste of money. Great idea, poor execution. Poor quality of materials. Don't recommend nor will purchase again.

The kit had all the parts except one, the installation instructions.

bent upwords into clutch cover case very disapointed

I'm happy with the tensioner with the exception of the longer bolts THAT WHERE NOT INCLUDED in the package... Be careful tho that the bearing comes in a small bag separate from the tensioner... Thank God I didn't throw the package away... Look twice... The ball bearing is in the package... But couldn't find the longer bolts as it says in the instructions that is posted with the item description.... Overall I'm happy with the product since I've gone Tru 4 tensioners (stock ones) and almost killed myself when they failed..THIS ITEM IS A MUST FOR TROBLE FREE CHAIN ALIGNMENT AND SMOOTHER ENGINE PERFORMANCE... I'LL BE BUILDING MORE BIKES AND I WILL DEFINITELY USE THIS PRODUCT... the original chain tensioner will be used as paper weight...

Added this to my Motorized 80cc Bike and it works great to date! The product was delivered quick and installation was fairly smooth. So Far so Good..... Fast Delivery and Good Product..... Thanks

Did not come with actuator berring as advertised.

Great product...but very pricey...a must have for your motorized bike...good luck trying to buy from Bike Berry, they cannot keep anything in stock?
