Italian transmission specialist PBR (near Bologna) sells all three of the key transmission components - the ones subjected to the greatest stress and wear - the front and rear sprockets and, of course, the chain.
One of its great successes has been with the application-tuned matched kits they offer dealers and, seen here, is a new for 2020 street transmission kit, the 'Black & Gold', which is said to include the best of all three components.
The 'Black & Gold' EK QX-Ring SRX2 offers "exceptional on-road performance and is EK Enuma's top model. The Japanese manufacturer's brand is a guarantee of quality and reliability and has been known for decades for its quality and cutting-edge transmission chain manufacturing technology.
"EK Enuma chain holds many of the most important patents in the motorcycle chain market and the Quadra X-Ring technology reduces friction while significantly increasing the transmission contact duration - not an easy combination to achieve.
"The lightened plates improve performance and the 'Black & Gold' bi-colour format is recognised worldwide as a quality hallmark."
The anti-corrosion black PBR C45T rear sprocket is precision-manufactured in zinc-coated carbon steel and is PBR's top rear sprocket for street, naked and touring motorcycles, developed in collaboration with several leading MotoGP and Superbike teams.
High-frequency induction hardening makes the sprocket teeth very strong and ensures the optimum chain contact endurance - the duration is guaranteed for over 25,000 km if the correct maintenance is carried out after each 1,000 km. PBR says that its duration is 300% greater than normal (not tempered) rear sprockets.
Finally, completing the kit, the RSS front sprocket (Rubber Sprocket System) is manufactured in tempered steel with an extremely high-strength rubber insert for "extraordinary fluidity and quietness".
"The rubber lasts a very long time, and the strength and quality of the material used prevent the problems sometimes encountered with the glue when lower grade materials are used, preserving the same consistent performance and reliability during its extensive lifetime even after many thousands of kilometres."
The PBR 'Black & Gold' kit is available for all sport, street and Enduro/off-road motorcycles of middleweight and large capacity.
Founded in 1969, PBR says it was the first specialist (rear and front) motorcycle sprocket manufacturer in Italy, specialising in very short lead-time production with applications for more than 3,368 models in its catalogue, with nearly 10,000 items in stock and ready to ship at any time.
With more than 50 years of product testing and a long series of world championships won in Motocross, MotoGP, Superbike and SuperSport, PBR's race pedigree goes deep, developing a new kit with a special 428 chain pitch and creating a new rear sprocket in titanium for its MotoGP teams.
"It's not only about racing though," says PBR. "The 'trickle down' has meant a leading position among transmission component suppliers for street and off-road riders worldwide and OEM sprocket contracts with many leading OEMs, including KTM, Husqvarna, Aprilia, Piaggio, MV Agusta, Fantic and Sherco."
