exactly my point, mcguiness, legend on the roads, i think its useful there, just in general actual circuit racing i know most barely touch it unless its to tighten their line mid corner. my brother in law rides in the ducati 848 evo challenge, former bsb superbike cup rider, superstock 1000 for 4 seasons, superstock 600 and 125cc championships. he has a thumb operated rear brake as most of the paddock do. all the other riders we know and spk to have slight differences. i know leon haslam never ever uses it until he has had to learn just recently to attempt to ride round a problem with his bmw, but sam and alex lowes, jon kirkham, barry burrel, kenny gilbertson, tommy hill, stuart easton and steve plater all only use mid corner. i think its generally the riders these days that have better electronics packages that will use the rear brake under heavy braking, as the guys i know in circuit racing just complain that when braking heavy with the front it just locks the rear so easily as the rear is barely even in contact with the track. it would be interesting to find out what other road racers say as i wonder if they share mcguinness's preference of using the rear aswell on the road but not so much on circuit. ill have to ask around at the next race wkend im at!
