HANDLING NOTE
WARNING
This rear shock absorber contains high-
pressure nitrogen gas. To prevent the dan-
ger of explosion, read and understand the

ble for property damage or personal injury
that may result from improper handling.
1. Never tamper or attempt to open the
rear shock absorber.

into an open flame or other high heat.
The rear shock absorber may explode
