Gear wheel first gear Sachs 502 503 50/2 24 teeth special

Gear first gear Sachs 502 / 503 / 50/2 24 teeth

This is a special gear, newly calculated and designed and fits perfectly in the gearbox of Sachs 503 / 502 and 50/2 . The opposite sprocket (2nd gear) remains the same! It is for the first gear and has only 24 teeth instead of 25 (or 27 depending on the type). This makes the first gear 4% longer (or 11%). 

The combination of the special first and second gear cog (see related products)makes the engine's gearbox ideal for racing purposes. Example: If you shift from first to second gear at 11,000 rpm, you're at 7615 rpm. Without the two special gears, you would only be at 6,700 rpm. This can make a difference of 2 hp.

Ideal for cross, race, sprint, or for bikes with greatly increased power.

Tip: after 1 tank of fuel used, change the gearbox oil. This is because minimal wear particles may remain in the oil.

Absolute top quality and a unique product!
