PBR Sprockets has added to its range for 2018 with an innovative approach to the chain sprocket, taking its steel sprocket and injecting the drilled holes with rubber.
The company says that the result “is a combination of an extremely high strength sprocket that handles the power with an extraordinary fluidity and quietness” - almost a semi-isolation mount effect in terms of the interface between the energy dissipation from the chain and the sprocket body and shaft.

“Compared to the conventional bonding and use of glue, the long-lasting rubber ensures the same reliability, but eliminates the problems that can be encountered when making sprockets with glue seals.
This new design is exclusively available from PBR for all street and race models and the more powerful off-roaders.
Also seen here, PBR’s line of tempered carbon steel C45 rear sprockets for street bikes has been expanded with new applications for 2018 street sport bikes.

PBR says its production process involves an induction temper on the whole of the sprocket teeth area, making it more resistant to sprocket wear, improving chain life and improving the reliability of chain/sprocket settings on long distance journeys and in between service intervals.
For off-road applications, PBR’s all-new precision CNC-machined C45 steel C-Light rear sprockets are said to “feature all the latest design and manufacturing advances and technical innovations to ensure robust yet lightweight sprockets that can handle the serious duty demands placed on them”.

Said to offer improved quality and reliability, with an attractive weight reducing hole design, they are available in different sizes and colours and can be combined with PBR’s front sprockets range on Enduro and two/four-stroke Honda, Kawasaki, Suzuki, Yamaha and KTM models.
