…the heavier the bike, the more important it is to keep that engine engaged and in control of the rear wheel braking. If I came into a corner hot with my K100RS and pulled in the clutch to use only brakes to slow down, I’d be into the rhubarb or guardrail for sure! either that or the rear brake would do little at first and then lock up the back wheel uncontrollably. Given a choice between only the engine to brake the rear wheel or only a rear brake, I’ll take the engine any day.
I had a complete rear brake failure on a TY175 in the first loop of an event and after a much better rider said “ride without it, you don’t need it anyway” I persevered and finished the event with a second place position. He was totally right and I learned from that experience, I had been over using the rear brake all along. The front provides the lion share of the brake force and the rear just needs enough force to hold the rear wheel from passing the front! Using the engine to brake is like having anti-skid rear braking. :(as long as the engine doesn’t stall or lock-up completely)
