I needed a new front tyre on my VTR250 recently so I thought I'd give my max braking a real workout so that if I flat spotted the tyre, I was about to replace it anyway. For the life of me I couldn't lock up the front wheel. I did about a dozen of these full on both brakes from 60 kph and never locked up once. I wasn't trying to lock up the back at any stage. I sure smelt burning rubber but I never left any on the tarmac. I had to bring the testing to a halt as I became very motion sick. I thought I had a pretty strong forearm grip and I was using all four fingers. The pads were nearly new. I was doing it slightly uphill.
