In the list above, when not indicated, the item is for standard chain.
PBR manufacturers in Italy and sells motorcycle sprockets (front and rear sprockets, chains and complete kits) and wide range of accessories (handlebars, clip-on handlebars, handlebars weights, handlebar clamp kits, bike stand knobs, chain grease and cleaner, crash pads and mecdraulic).
We take part at the most important national and international competitions and events.
Thanks to our presence on the international markets, our well-know brand, our competence and our service we are the first choice of the major market operators.
All this could be enough to sum up our activity during the last quarter of century, but it is also right to mention that this is the result of years of research and development, tests, technical improvements, careful selection of raw materials and production processes, combined with the manual ability of specialized craftsmen along with the high precision of CNC industrial technologies.As a result, special productions of prototypes and models for racing purposes are possible together with series production capacity for the industrial market.
Remember to select the right ratio in the products options.
Front Sprockets (counter shaft) are made of chromoly steel, machined all over for accuracy. Many of these are available drilled and machined for lightness. (normally 520 and 415)
Rear sprockets are essentially two types: stainless steel and aluminum.
Every sprocket is made on precision, computer controlled equipment. The teeth are machined to the latest standards, for maximum chain life and more efficient power transmission. The teeth and the outside diameter are cut at the same time. This makes sure the teeth are concentric to the sprocket center.
Every sprocket is made from heat treated 7075-T6 aluminum, hard anodized finished for extra durability
- Steel: ideal replacement of the OEM part, where quality is not better is the same of the original.
Every sprocket is heat treated through an induction hardening then tempered to produce exactly the correct hardness for durability and efficient power delivery. To correct any distortion that may have occurred during these stages, the sprockets are put through a special flattening machine. For corrosion resistance, the steel sprockets are bright zinc plated.
- Aluminum: the max for those who want to light final transmission or have on board an accessory that on expert riders have. Usually we have on stock 520 or 415 sprockets but original pitch could be ordered.
Made from heat treated 7075-T6 aluminum we offer them only hard anodize finished for an extend life time.

By choosing the ratios, 1 front sprocket cog is equal to about 3 rear sprocket cogs (the exact ratio is given by: number of rear sprocket teeth / number of front sprocket teeth).
The above stated, ratios have to be chosen in a way that a max. difference of 2 cogs is not exceeded. This way, you can always keep the same chain length. The Kawasaki ZX-10R Ninja is an exception: a rear chain with over 1 tooth more than the stock one cannot be used, since length of stock chain will not allow that. Remember that if you want more acceleration you have to mount a rear sprocket with more toothing, or a front sprocket with lower toothing. Ratios have to be necessarily and exclusively chosen by yourself. It is usual to mount a rear sprocket with 2 teeth more than the stock one, but that is however a medium choice which does not mean to be satisfying to everybody.
In a circuit, generally the right final ratio will be that allowing to achieve, at the highest gear, about 200 rpm more than the max power rate, always staying 200 / 300 rpm under the maximum rate the engine can reach. This way, you can take advantage of the trail of the driver who is preceding you.
Choosing the final ratio, remember that the bigger it is, the more the acceleration will be. But if it is too big, you will lose speed. If on the contrary the ratio is too small, you will lose acceleration and will not manage to reach the maximum speed.
If your final transmission has exceeded 5000 km, we advise not to change only one of the three components, but to change them altogether (chain,rear and front sprockets). This, because final transmission would otherwise deteriorate in very few kilometres.
For the best working and longer duration of the transmission, it needs to be cleaned and lubricated every 1000 Km at least, using our specific cleaner and lubrificant for chains that you find here.
