It can definately be challenging, especially if you don’t do it often (which Gary mentioned). There’s a lot going on and drivers can be unpredictable. But two things you can always expect is that the guy in front of you is going to slam on his brakes and the guy to the right of you isn’t going to see you and is about to lane change on top of you.
Sport bikes may be more top heavy than similar sized cruisers. I know my Concours carries alot of weight up high, especially with a full tank (7.5 gals). But even riding a low slung cruiser won’t help if you get frozen by a situation. A moped with a frozen rider in the same situation is going to hit that stopped car just as fast as a sport bike.
I’ve been there before and it happens really fast: I’m in the second lane, stop-and-go parking lot speeds, looking over my left shoulder for a gap to jump into the fast lane, glance forward and the guy if front of me has stopped. From experience, I’m already covering the front and back brake because I have to half expect this to happen. And when it does, it’s the rear brake I hit first as it’s less likely to cause me to drop the bike than smacking down the front with the front tire all cockeyed. I’m also covering the front, but use it only when the bike is settled and/or it’s essential to avoid mounting the car in front of me.
I also agree with Gary on the crampbusters. I thought about getting one a year ago when my wrist was bugging me. But I didn’t like the added complexity. I also like to range my hands in and out on the grips and don’t want to have to think about where the paddle is. Ultimately, I just introduced some hand and forearm exercises into my admittedly infrequent exercises and now my wrist is good for at least 90-120 minutes at a stretch. By then I’m usually ready for a pitstop and stretch anyway.
