Improve your bike’s handling, ride – and safety – with some suspension upgrades.

Adjusting motorcycle rear shock preload

by Jim Blackstock |

Forget about engine tuning or performance pipes if you want to make a dramatic change to your bike’s performance. If you’re looking for something that’ll affect every aspect of your riding, pound-for-pound, suspension upgrades make the biggest difference.

Whether your bike is brand new or a 20-year-old hack, a touring machine or naked, there’s always something that can be done to the suspension to either improve it or make it work better for you.

The trouble is, suspension is also something of a black art and commonly misunderstood, which is why so many turn instead to experts such as K-Tech or MCT to do it for them.

If you don’t want to go that far, however, there are a number of relatively simple things you can do – or buy – to upgrade your ride.

However, if your bike is older, perhaps worn, or with more basic suspension, there are plenty of things you can do such as upgrade your front forks via a kit or even replace your rear shock with a higher spec, adjustable item that can give a dramatic improvement to your bike’s handling and ride – and your enjoyment and safety.
