Oil level adjustment<br />
Compared with conventional type of front<br />
forks, the upside down front forks are very<br />
sensitive to variations in oil level. Therefore,<br />
adjust the oil level with special care.<br />
A change in the fork oil level will not affect<br />
the spring force at the beginning of the fork<br />
travel, but will have a great effect at the<br />
end of the travel.<br />
When the oil level is raised:<br />
The air spring in the later half stage of<br />
travel is stronger, and make the front forks<br />
more progressive.<br />
When the oil level is lowered:<br />
The air spring of the travel is lessened, and<br />
thus the front fork less progressive. The<br />
oil level works most efficient at the end of<br />
the fork travel. Air spring characteristics<br />
shown, is a general card description to understand<br />
the difference when the oil level is<br />
changed.<br />
NOTE!<br />
Adjust the oil level in mm according to the<br />
fi gure with the fork leg fully compressed.<br />
For the right oil-level, please see the specifi<br />
cation card.<br />
Air spring characteristics<br />
Air inside the front fork works as a spring.<br />
The graph at the bottom of the page shows<br />
the spring force related to stroke when the<br />
oil level is changed between 140 mm and<br />
200 mm. Standard oil level is 180 mm.<br />
