Not often required with an SR500, right?!

If you have a drum-brake rear end, the length of the actuating rod is exactly the same length as the rear shocks, meaning if you break a shock on a trip, you can limp home, albeit without a rear brake, but also without the rear wheel wearing through the mudguard!

If you break a throttle cable, you can limp home by replacing it with the throttle return cable.
