Feature: paul pitchfork - advanced training Level One is all about cornering. The exercises - taught over five sessions of theory followed by track time - took us through throttle control, identifying turn points, quick turning, rider input and what the school calls ‘two step’ - identifying your turn point then switching your focus to the apex before entering the turn. But what the day is really all about can be boiled down to one thing - achieving a stable bike throughout the turn. Each track session left me feeling that my riding skills were improving exponentially, but it was the theory covered in the classroom that absorbed me most. It made so much sense, and I wished I’d known it all at the very start of my riding career. The first ‘Golden Rule’ we were taught was the need to roll on the throttle smoothly, evenly and constantly throughout the turn. A simple instruction, but there is so much science behind it. We were shown that the bike’s suspension, both front and rear, extends when you accelerate (we all assumed the shock compresses). Constantly rolling on the throttle counteracts the forces which would otherwise slow the bike in a turn and applies acceleration, thus ensuring the suspension remains at its mid stroke where it is must be to operate optimally. This also maintains good ground clearance to allow the bike to lean in further. Applying acceleration also shifts the weight back on to the rear tyre, which has a greater contact area In the pit lane, starting a session with the ground and thus more grip. We were also taught the importance of rolling the throttle on only after you’ve steered the bike into the corner. This ensures that the bike is decelerating at the point of turning and the forks are compressed, thus changing the geometry of the bike and shortening the wheelbase. This assists the front end to tuck into the turn and bite. All this was explained to us in the first twenty- minute classroom session. As we waited our turn to get on to the track and start applying the theory, I continued to think through what we had learnt and saw its application to adventure bikes. With a longer wheelbase, greater rake in the forks and often a twenty-one inch front wheel, an adventure bike needs more help turning than a sports bike or street bike. Furthermore, the suspension on an adventure bikes has more travel and is usually softer, so the effects of acceleration and deceleration would be accentuated. Perhaps, I wondered, there would be benefit approaching a corner a little faster and braking a little harder, to compress the forks more and amplify this geometric shift, thus sharpening the steering? I wouldn’t know until I tried it, but already this newly-acquired knowledge had got me thinking so much more about my riding - and the science behind it - than ever before.
