Hyper reinforced: With a chain RK 428 KRO HYPER Reinforced
Hyper reinforced O-RING: With a chain RK 428 XSO HYPER Reinforced O-ring, therefore with seal which maintains the lubrication!

The pinion and the crown are cut in the best materials for a quality and an optimal lifespan! You should know that the original 50cc MASAI quads are equipped with a fairly low range chain kit (identical to the first price here), and a final transmission in 13X32! You will choose a bigger pinion or a smaller crown gear for more top speed, and a smaller pinion for more acceleration! Be careful, a longer chain kit is more difficult to upgrade, so plan at least an exhaust line and a sport air filter to get a tooth or two more sprocket. A tooth at the pinion is approximately equivalent to 5 teeth at the crown! The best for speed is to use a smaller crown which will also be lighter and therefore easier to carry!

Example :
If your speed in 13X32 teeth is 65 KM / H at 10,000 rpm
It will be: 72KM / H in 14X32 teeth at 10,000 rpm
It will be: 79KM / H in 13X28 teeth at 10 000rpm
It will be: 80 KM / H in 15X32 teeth at 10,000 rpm
It will be: 88KM / H in 14X28 teeth at 10 000rpm
It will be: 88KM / H in 16X32 teeth at 10,000 rpm

It will be: 95KM / H in 17X32 teeth at 10 000rpm

It will be: 96KM / H in 15X28 teeth at 10,000 rpm

It will be: 103KM / H in 18X32 teeth at 10 000rpm

It will be: 105KM / H in 16X28 teeth at 10 000rpm

It will be: 111KM / H in 19X32 teeth at 10 000rpm

The more you want to pull a long chain kit, the more power you will need! To pull a 15/28, you need at least a muffler, powerful 70cc kit, 21mm carburetor, sport variator (set to pull around 10,000 revolutions), racing valves ... To pull more (a 17/28 for example), a long stroke crankshaft with a very powerful kit is recommended!
