Manufacturers make a distinction between load (riding solo or with a pillion passenger, with or without luggage) and speed (on secondary roads or motorways). It is advisable to always ride at the highest pressure level recommended by the motorcycle manufacturer. Some amount of comfort will be lost, but that loss will be outweighed by improved safety. In addition the rolling resistance will be lower which will help to save fuel. Incorrect inflation pressure reduces the service life and may have a negative influence on the riding characteristics of the motorcycle. Under-inflated tyres flex excessively, easily overheat and can suffer damage. Over-inflation can cause uneven wear. Improper inflation, either too high or too low, can adversely affect overall handling and ride quality. Tyre pressure is measured when the tyres are cold. During riding the tyre becomes warm and the tyre pressure is therefore higher (up to 0,5 bar). The tyre pressure should not be reduced as it will automatically decrease again as the tyre cools down. Please note that the maximum load of the tyre depends on the inflation pressure. This means that you have to increase the inflation pressure up to the maximum pressure stated on the sidewall of the tyre to achieve the maximum load carrying capacity.
You can find the load index of a tyre on the sidewall. This index shows the maximum load of a tyre. Never exceed the accessory restrictions and vehicle load capacity found in the motorcycle owner's manual or the maximum load moulded on the tyre sidewall.
130/90 - 16 M/C 67H TL/TT
In this table you can find the speed index and the conversation to km/h and mph. This index stands for the registered maximum speed. You can find the speed index on the sidewall of the tyre.
The size of the chain can usually be found on the side of a link.
Generally sizes are referred to as 'pitch X length'.
Example: 428X114 - pitch of 428 and chain length of 114 links.
The distance between the chain pins is referred to as the ‘Pitch’.
Standard Chain: is a regular chain suited for smaller road bikes. (125cc-250cc)
Heavy Duty Chains: popular for mid- sized road bikes & most MX bikes.
O-ring Chain: Suitable for most road bikes over 400cc & also for MX/Enduro use. They retain lube better than HD chains.
Z-ring or X-ring Chains: Both retain grease longer than an O-ring due to the shape of the rubber rings.
Road bikes: Lubricate chain every 500-800 km’s.
Off-road/motocross bikes: Depending on riding conditions, however lubrication recommended after each ride and after each high pressure clean. Allow chain lube sufficient time to dry before riding again.
The motorcycle chain's appearance will be a good indicator of when to change your bike chain. If it's stretched or twisted, it's time to change your bike chain. You should also take a close look at the chain links, making sure that they're not worn. If they are, change them.
Always replace the chain and both sprockets at the same time. A worn component will shorten the life of the rest.
