I have to respectfully disagree. I've been a licensed rider for 36 years and a Canada Safety Council motorcycle riding instructor for 18 years. We tell our students time and time again that it is a myth that one needs to be able to get both feet flat on the ground when you straddle the bike. At 5'8" and a 30" inseam there would be a whole lot of motorcycles off my list if I had to follow that rule. I have an '06 FJR with a Seth Laam seat and cannot touch flat footed when sitting on the bike - It's close, but not flat footed. I ride two-up with my wife regularly and that includes multi-day rides with the bike fully loaded (heavy). How do I do it, you ask? I stop in the Ready Position 90+ percent of the time. That means left foot down, right foot on the brake, clutch pulled in, and right hand on the throttle so I'm ready to go, just as the name suggests. We teach this method to our students as best practice and it really is that. I've seen too many students who like to stop with both feet down, then when they start to move off from a stop if for some reason they need to come to a quick stop before they get their feet up on the pegs they have all their weight on the seat and only one brake to do the stopping - the front brake. This is particularly hazardous when making a turn at an intersection if at the last second a pedestrian, E-bike, skateboarder, or whatever decides to step, jump, run, or ride out in front of you. Front brake only on a slow turn at an intersection is a recipe for disaster. The ready position also allows the rider to "scooch" their butt over so they can get their left foot flat on the ground supporting the bike. Yes, sometimes the rider may need to put their right foot down instead if there is a pot hole, or the road surface is uneven but again, most of the time they should be able to stop with their left foot down. What I find with many "experienced" riders and most often with cruiser riders is that they like stopping with both feet down because they feel as though it is more secure and stable, but it really is not, for reasons that I previously mentioned. OK, it's after midnight here and I need to shut down. I appreciate any comments and feedback.
Well, I have to agree with Mopheadama, and disagree with you, but for different reasons.
Flat footing a bike with only ONE foot is dangerous, because if you're depending on that ONE foot (with the bike leaned that way) to stabilize you, you are in trouble if that foot slips on oil, gravel pebbles, etc. You lose your balance and the bike falls. Not good.
Plus, as we age, we get to the point where we can't always balance with only ONE foot/leg. We need two feet and legs to balance. I'll even go as far as saying that if you need help balancing an FJR1300, you're on the wrong bike...FOR YOU. An FJR is not a heavy bike. It's a lot lighter than a Honda ST1300, at 730 lbs. Top heavy or not, that's still about 100 lbs lighter than the ST1300, isn't it? It's been a while since I checked the FJR weight specs.
