I've thought this before, several times. And again this morning.
When a car pops out at a side street ….and is still rolling....The Most Powerful Brake is in the hand which is already occupied doing something else - the Throttle! That split second delay of getting out of the throttle could be meaningful.
This is wrong.
The left hand is free from other duties and can very, very quickly be brought to bear on what should be the most powerful brake - the front tire - while rolling off the throttle with the right hand.
Bing - Bang. And you're stopped.
As it exists now - a sudden hard grip with the left hand will either lock your rear tire - or do a gentle not-a-lHELP-of-a-lot
if you have a drum brake back there!
I don't give a Rat's Patoot that the clutch is in the L hand on motorcycles - ….. I'm not riding a motorcycle.

Also for anyone who goes back and forth between cycling and scootering, you may have an embarrassing flight over the bars on your first decent back on the bike. Yes, this is experience. I swapped the brakes on my bicycle but am considering swapping the scooter brakes. I usually have the scooter brake covered and operate the throttle with the the thumb and first finger pocket. I have a lights throttle setup on the scoot.
-
I ride scooters, motorcycles and a bicycle. I completely disagree, the front brake should absolutely be on the right side on scooters. On bicycles it makes no difference but I have considered swapping mine to front brake on the right side.
So why should a scooter have the front brake on the right side? For one thing an lot of scooter riders also ride or rode motorcycles and it could be confusing.
More importantly. The rear brake on a scooter is typically more important than the rear brake on many street motorcycles. Scooters tend to have a lot more weight on their rear tire than motorcycles. They also tend to have less powerful brakes than motorcycles, not always but often.
So, when you first start to brake on a scooter, your rear tire has more traction and potentially more braking force. Many scooters with front and rear disc brakes have the same size disc front and rear.
As you brake weight will shift to the front wheel and it now has the greater breaking potential. Most scooters do not have the braking power to shift weight to the front tire as some motorcycles do. On a sport bike or super moto you can do a "stoppie" and shift all of the weight to the front tire.
Anyway, a common cause of accidents is grabbing the front brake to quickly and sliding out the front tire. Many people like to start braking with the rear and then applying front as weight shifts and front tire can handle the braking force. I like to apply both at the same time and then squeezing the front harder as weight shifts forward.
I have only owned one scooter with a rear drum brake and it worked pretty good. My Like and Majesty both have front and rear discs. They would take much longer to stop if I used only the front brake. Yes the front brake is more powerful but the rear brake is still very important. My Like has a combined braking system so when I apply the rear brake it also applies some front brake. I don't like the system but it does make that left lever more powerful than the right.
Putting the front brake on the same size as the throttle is better in that you are naturally likely to roll off the throttle as you grab for the brake.

All good points.
The issue with drum brakes like my agility is how well they are adjusted. Properly tuned the Agility's and almost any drum brake should be able to lock the rear wheel. I have grown used to only using the front brake as the rear drum on my scoot is out of round. I also prefer the front brake for its precision(being hydraulic). I had to do some brake tests right after I got the bike and in emergency braking the front will hold into a stoppie unless the front is on low traction pavement or is over the spec 17psi.
-
I have been riding long enough to know some hand shift bikes did/could have front brake on left handlebar.
Standardized controls are better.
Ride by paying attention ----and panic stops not required.
-
My emergency brake tests were done in a controlled environment AKA closed course. The only time I have had to use maximum braking in almost 20,000 miles was when a Dodge Charger floored it in reverse out of a driveway for a J turn into the street. The idiot blocked 2 lanes in about a half second.

That's great if your front brake works that well. What if the road is slick or you're on gravel? Sometimes that rear brake is pretty important.
-
Agreed, that rear brake is very important! I ride about 10miles of gravel a week and the front 12 inch wheel will barely track when turned much less have any brake force.
-
Those of us that have spent time aggressively riding sport bikes on our favorite twisty roads and on the race track, are familiar with riding with one finger, sometimes two, on the front brake lever along with working the throttle. Upon corner entry, instead of grabbing a handful, you apply lightly the front to set the suspension, transfer weight to the front therefore increasing front contact patch. And at the same time trail braking the rear upon corner entry and apex. Good riders do this on track and street with no problem
-
Rode dirt bikes for years and use to the front brake being on the right hand as well. I would be messed up if it was on the left hand.
-
All interesting points taking in the obvious exceptions.
However -
Most of us ride a scooter only on pavement.
Most of us do not switch back and forth with motorcycles to scooters.
Most quick stopping is needed with the scooter in an upright position.
The rear brake is best for slow speed maneuvering, and low speed braking...the rear , with a disc, can lock first on heavy stops.
The front wheel is the king of serious braking - even on a scooter - see the twin front discs on big, heavy scooters.
When a scooter has single wheel ABS - it is on the front wheel - always.

I was watching his lessons 3 years before I got the scooter. I enjoy thoroughly learning new skills more than just about anything. Total Control 2nd edition by Lee Parks was the best technique source I have found. It made me feel like I was on the wrong bike though.

SAFE BRAKING ON A SCOOTERUsing your same logic People who ride both scooters and bikes would in a panic situation would be grabbing the rear brake instead of the front. Think of it as switching the brake and gas pedal on a car and the resulting Kaos, ingrained memory (I know poor example of throttle and brakes). I'm glad they are standardized. Of course I have yet to do a stoppie on a scooter. I don't know if it's possible with anti-lock brakes and the weight distribution favoring the rear. All the Xictings and People S have dual caliber brakes which have some serious braking ability with rear disc brakes as well. Even my little Lambretta Uno 150 has front and rear disc.

While the front brake is by far the most important in heavy braking in most situations, I don't see why means it should go on the left lever. You claim you could apply the front brake quicker if it was on the left lever. I don't see why that would be. Also, applying the front brake too fast can result in sliding the front tire and that's generally much worse than skidding the rear tire. Generally it's best to apply both brakes at the same time and then increase pressure on the front as weight shifts. Also, even if you don't ride on gravel, you may end up on pavement that's slippery for some reason and then braking from the rear wheel becomes more important.
I think that switching the brake levers would be bad for most riders. Maybe it would work better for you. I'm sure there's a way to make the switch if you really want it.
-
Whatever floats your boat I guess. I do regularly switch between my scooter and my motorcycle, so I'll stick with a RH Front brake lever.
As an aside, I well recall just after starting scootering and returning to the bike after a lay-off, hitting the clutch instead of the rear brake on the approach to a fast bend! NOT recommended and very nearly change of underwear time. These days I rarely use the rear brake on my scooter to de-wire the neurons that caused that heart-stopping moment.

Today you have been proven to be correct. I barely applied the front brake at a stop sign after engine braking and the hard, stock front rubber, went out from under me. First rain on fresh pavement.

I hope you didn't get hurt and your scooter wasn't damaged.
I have had my front tire lock up under braking before. Four of those resulted in crashes, two times was on dirt or gravel once on rain&oil on the road, and once on a wet wooden bridge. I was a sport bike rider for many years and hardly touched my rear brake. When I started riding off road my sport bike habits got me into trouble a few times. Riding off road on less than ideal traction really helped me learn how to properly use my brakes. Now I adjust how much front and rear brake I use depending on the bike I am riding and the road surface.
On really slippery surfaces I often use only the rear brake.

Most of the scooter riders I know do switch back and forth.
-

Yep. I think most of us have learned that valuable life lesson!
-
"Most of us do not switch back and forth with motorcycles to scooters."
I switch back and forth between the two. I've done it for years. So for me, some consistency between control layout is good.

That depends on how you define "us". In my experience many motorcycle and scooter riders do not have a clue on how to properly use their brakes. Probably the most common mistake is under use of the front brake. There are many riders who believe the front brake will "put you over the handlebars". Over use of the rear brake is also common as many people will lock up the rear brake and sometimes end up crashing from that.
The dynamics of braking on a bike is not the simple. It takes understanding the dynamics of braking as well as practice to get it right.
I think I understand the dynamics and I also practice but I doubt I can get 100% out of my brakes except maybe my Like 150i which has ABS. Actually, even with ABS I doubt I can get 100% because ABS generally isn't perfect either.
-
I think most long-term riders have a good idea about braking and proper use. People who have competed in racing for sure. I can remember doing stoppies on my Enduro at a early age, (balancing the bike on the front tire on a front brake stop).
The factor that comes into play between a motorcycle and scooter is weight distribution. Way easier for the front tire to wash out on a loose surface.

This may vary slightly from the topic, but what 120/70/12 tire has the highest gripping compound for wet or dry conditions? life span is not a concern as my front tire has very little weight on it and seems to last about 5-6 times as long as the rear.
To add to the topic, the knowledge of theoretic optimal technique for any skill never seems to be equaled by the level of practical understanding. Once we obtain the knowledge through study experimentation etc, true understanding(in the context of braking) as klaviator stated takes time and practice. Even the best riders(who's skills are beyond what I could ever dream of attaining) fall short of mechanical perfection. I believe all of us have room for improvement, but at some point near the limits improvement cannot be gained without reaching the limit which is not possible on streets and is therefore irrelevant to us normal scooter riders. I do agree that a very low percentage of riders have a thorough base knowledge or understanding of proper brake use. I will have logged over 20,000 2 wheel miles at the end of the month and although I have studied the theories of frictional values and mass vectors for several years I am now just beginning to see how little actual practical understanding I have.
I am looking forward to many more years of riding and hopefully learning along the way to become a better and safer rider.

With your attitude you will become a better and safer rider. There are some riders out there who think they have it all figured out and never get any better. After 40 years and around 500,000 miles I am still trying to improve my riding skills.
As for the best tire for traction, that's hard to say. I'm a fan of the Michelin City Grip. There are stickier tires out there in dry conditions but in wet conditions its hard to beat the City Grip IMO.
-
Definitely seems like a popular tire choice. I will try them out for my next set.

I have tried them on all my scooters. My biggest problem with City Grips is they have never come in the right size for both the front and rear of my scooters. I recently put Pirelli Angels on my Like. They stick really well but don't ride as nice as City Grips.

I will see what they have for 130 and 120/70/12.
