Why does carrying a pillion turn my R1 soft?
When I’m out on my 2010 Yamaha R1 two-up the back end is bouncing around when I’m accelerating out of bends, especially on rougher road surfaces. The front also feels slightly soft. Russ Woodhead, email
Answered by Gareth Evans, Reactive Suspension Both the preload and rebound damping will need to be increased to accommodate the extra weight of the pillion. Rebound damping controls how fast the stored energy in the spring is released. Having the extra weight of a passenger means the spring is compressed more over bumps and under acceleration. As it’s being compressed more it has more stored force, so needs more rebound damping to control the release of energy which you are feeling as ‘bouncing around’.
There are no fixed values I can give you, as how much extra preload and rebound required depends on the weight of the passenger. Write down what your settings are for solo riding, then make small changes until you get the ride quality that you want. When you’ve got a setting you like, write that down, then you’ll have a solo and two-up setting.
Although I drive a taxi for a living, my personal transport is a bike – no car. I need a camera I can attach to my Schuberth C3 flip helmet, and then be mounted in the taxi for working hours. I’m not on a budget as I would prefer something unobtrusive rather than a big box hanging off my helmet! Des Southon, Hove
Answered by Tony Hoare, MCN If you want a dashcam that constantly takes in footage and then stores it in case of a collision, you would be better off buying two separate cameras as the two jobs are so different. A bike-specific camera needs to be waterproof and also have specific mounts, which increases the price significantly. The bike-specific Nextbase Ride is £249.99 and won’t work well in a car, while Nextbase’s entry-level car dashcam, the 212, costs £69.99. Buying that will leave you plenty of cash to buy a simple camera to use on your bike. The Gopro Hero Session (£159.99) is a good option, as is a Drift Stealth 2 (£99.99), which allows you to retrospectively store the last few minutes of footage, rather than having to delete the boring bits at the end of each ride.
Adding more rebound damping will give a smoother two-up ride
