Motorcycle maintenance, on and off road
An off-road engine is not serviced by distance. One hour on a track at high revs tires the machine more than fifty kilometres of open road, which is why every off-road manufacturer publishes its intervals in engine hours. That only works if the hours are actually counted rather than estimated.
The guides collected here follow the same pattern: the manufacturer interval, what shortens it (sand, mud, revs, rider weight), and the visual cue that lets you decide without stripping anything down. Oil and filter, two-stroke top-end, four-stroke piston, valve clearances, pads, air filter, chain and sprocket, coolant, suspension.
The thread running through all of them is the log: a job recorded the day it is done, with the hour reading next to it, is worth more than a rough memory on the day you sell.
