[QUOTE="Eddie"] Probably not much, depending on how shite-encrusted your rear brake pistons are. On your bike, I doubt there's much point using it for any of those things. On other bikes, with a different weight distribution and geometry, the back brake can help quite significantly.[/QUOTE] I've always used the back brake... and when I've tried braking just using the front, unless you're hammering that as hard as possible and thus transferring any useful weight to the front end to that extent, the back does make a bit of difference. Having said that, I don't tend to use the front all that much when doing <- 10mph in heavy traffic etc. - the bike is much more balanced, and I can come almost to a standstill without having to put a foot down, due to the balance of the bike not being upset by the compression of the front forks etc. To put it another way... try and do a figure of eight like they get you to do (or at least did), on your CBT, first using just the front brake, and then just the back.
