Advanced training is mostly based on Police Motorcycle Roadcraft and Police Class 1 riding standards.
Roadcraft doesn’t cover in any detail modern advances in motorcycle design and dynamics, which present new problems and opportunities.
Cornering in particular is somewhat over simplified, no particular ‘lines’ are suggested (since the 1970’s version of Roadcraft) apart from riding around the outside of corners to get a better view ahead. The problem with this, is it puts you close to the scenery or oncoming traffic all the way around the corner.
There are techniques that are routinely used in road racing that can be employed in an emergency, particularly trail braking using the front brake into corners, when you misjudge your entry speed, or encounter a hazard before you enter.
Learning how to change body position to increase ground clearance when leant, can be vital on many bikes, and can be the difference to making it around a corner – or not.
Modern tyres have unbelievable levels of grip to most riders, who often lack the experience and confidence to lean a bike anywhere near as far as they safely could, again making them vulnerable if they need in an emergency to turn at a faster rate.
It is also important to be always in the correct gear, and not rely on ‘block shifting’ as you come to a halt. You can do this by employing a slipper clutch if you have one fitted, or blipping the throttle to match the engine speed to the lower gear on downshifts.
It helps if you are professionally coached in these techniques and others, and given an opportunity to practise in a safer environment than the road, if you are to be as safe as you can be.
