Backing It In in Cornering and Techniques Posted September 4, 2013 · Report reply Rear brake should not be used on the racetrack. PERIOD. I have heard this piece of advice a lot, normally geared towards riders new to the track that are using the rear brake without realizing how light the rear wheel gets under hard braking, and thus are in danger of highsiding the bike. Once a rider understands the dynamics of the rear wheel and weight transfer, it certainly seems possible that a rider could use the rear brake judiciously to break the rear tire loose and let it come around, and I have in fact heard of riders that do this - even one that had a hand lever installed to control the rear brake more accurately. A few years ago I went to a race school that uses dirtbikes to each roadracers how to 'back it in' and it was all done with the rear brake. It was enlightening and really a lot of fun. I do not recommend using the rear brake on a sportbike on the track (or backing it in, for that matter) because it is too easy to slide the rear tire and potentially highside, but I imagine there are experienced riders that can and do use the rear brake on the track... so I would not be so bold as to say "never"! I'd agree witrh this! Sliding the rear on a dirtbike at 30mph on mud is easy and great fun. Trying to transfer those new found riding/sliding god skills onto tarmac at 5x the speed is much, much harder! and I use the rear brake on my racebike all the time in the pits going to and from the track!
