TIGER FEET – RUST spends three days traipsing through mud and gloop in Wales to establish the dirt credentials of Triumph’s new 2018 Tigers SUSPENSION SMARTS – Top US suspension tuner Alan Stillwell starts his regular rider-help column (with tyres?!) SET SAIL – when the road ends, it’s that or fly. July Behl floats his away across the Darien Gap A FOOT SOLDIER’S TALE – Rick Kemp investigates the life of the TRF regulars… plus, of course, lots more We’ll blame the weather. Oh yes, it’s lovely right now, but when we had those bikes in the van, when we were sat at the airport waiting to flyaway for five days on the Iberian trails, what was it like then? A white out. So many frustrated plans... Still, somehow we did get three days in, skidding around in the dirt on the latest Triumph Tigers to lift our mood and raise our appreciation of these fine adventure bikes. So while this issue is – as South Eastern Trains might say – a little delayed, it is nonetheless in many parts glorious. Made with love and in the spirit of sharing. As ever, wishing you happy riding and reading. Jon Bentman (Editor, RUST)

Suspension Tuning STILLWELL’S SUSPENSION SMARTS #1 TYRES Following on from last issue’s huge opening salvo on suspension setup, this issue we start Alan Stillwell’s regular suspension column, explaining individual facets one by one so we all gain a better understanding. And he starts with tyres! You’ll understand why when you read on… Words: Alan Stillwell, Stillwell Performance Suspension Images: JB In my opening feature in RUST #34 I talked about the basics when tuning your bike’s suspension. Understanding your available adjustments, setting sag and finding a basic chassis balance. By now you should have some time on the adjustments you made and become comfortable with your bike in general. With that in mind, it’s time to take it to the next level. So, let’s dive into the next step in finding the optimum next level tune for your machine. We will assume that you have the clickers set in the best position for your overall situation as a result of your prior testing. Your spring rates are good, and your sag is within spec. If you have questions about these basics, refer to the first tuning article in RUST #34. The point being here, there are still several basic things you can do to fine tune the suspension and chassis after finding your baseline settings, and here’s the first: TYRE CONDITION, PRESSURE AND STYLE You might not think that tyres play an important role in your suspension performance, but you would be wrong. Think of your tyres as another critical part of bump absorption. The first tip is to choose a tyre that is designed for the type of riding you do. If you are an extreme terrain type rider for instance, choosing an ultra hard sidewall desert tire (because it was the one on sale) is going to set you back in performance. The different tyres from say, Dunlop or Bridgestone are designed with different sidewall stiffness that match their intended purposes. Motocross and desert tires tend to have very stiff sidewalls while GoldenTyre is on the soft and flexy side with their sidewall stiffness. Great for off-road, not so hot for desert and motocross. A stiff tyre transmits into an overall firmer feeling to your suspension, the opposite with a soft tyre. Keep that in mind as you select your knobbies. w www.rustsports.com 35
