negative, in situations when you must react instinctively. Having your brain not trying to differ between the two helps. I ride both motorcycles and bicycles. all my bicycles ive riden, ive switched front brake to the right coming from motorcyles first. IT MAY work for some. its easier for your brain to default to one vs remembering and picking from two.
anyways. WHY would you want to run a motorcycle with a front brake actuated with your right hand and then ride a bicycle and have the left hand for the front brake?
you arent switching the motorcyle. So why not run your cycle setup the same as your motorcycle? less issue, less hiccups. Why train for two movements vs one?
