Absolutely. IMO, motorcycle riding teaches you the perfect combination of defensive & agressive driving - in other words, knowing when to play things cautious/safe and when to crank the throttle to get yourself up/ahead/away-from/out of a potentially dangerous situation.
That's called a "Trial by Fire." Learn or die.
"Combining both brakes won't stop you faster" Yeah, WRONG. 
Only wrong if you can somehow keep the rear wheel fully seated on the ground under MAXIMUM braking force. I don't mean "Touching but gliding," I mean "Firmly planted." If what is called a "stoppie" is physically possible, then using only the front brake in the most efficient way possible provides 100% of the maximum stopping power.
You have this kind of braking force up front. What can the rear wheel possibly add? The above is too much braking; use less front braking force, just enough to make the rear wheel glide over the surface of the road.
The maximum braking force of the front wheel on an upright bicycle (not motorcycle) is about 0.5g (i.e. 4.9 m/s^2 or 16ft/s^2), while the maximum braking force of the rear wheel alone is 0.1g (i.e. 0.981m/s^2 or 3.2ft/s^2). The more force applied up front, the more weight comes off the rear wheel, thus the less friction produced by stopping the rear wheel (friction is friction coefficient times perpendicular force), thus at i.e. 0.4g you have absolutely no more than 0.02g stopping force in the back, and 0.42 is less than 0.5. Be mindful you can lift the rear wheel by the 0.5 mark, so you haven't maximized front brake efficiency until you've eliminated rear wheel braking force entirely. Maximum stopping force is at roughly 11% slippage in any condition, but the fact that the wheel is able to deadstop and flip the bike over it if the rider slides forward (if you push on the handlebars and stay seated, this likely won't happen) indicates that the front wheel is NOT skidding (at which point there is little braking force).
In various situations, front braking is undesirable. On bumpy terrain (ill-maintained roads etc), you can throw the bike either forward or in a random direction (loss of control); use partial rear braking. On long descents down huge hills you can overheat a wheel, inflating a tube beyond maximum pressure and causing a blow; modulate the brakes between front and back to allow heat radiation. Of course if the front wheel is blown, stop with the rear. In slippery conditions, more control can be had with some rear braking, sometimes; more braking force can usually be had due to lack of friction limiting efficiency to a point that the rear will not lift off the ground (at least not as soon), and indeed it's the total force that causes slippage (thus the rear wheel can reach more of its maximum braking power than the front wheel, since its maximum braking force is lower).
Motorcycles are not bicycles. Motorcycles work
exactly the same as bicycles; however, they are larger, heavier, faster, have a better contact patch with the ground, etc. Sam exact dynamics, but the numbers we're using here are much different. Launching a motorcycle end over end by locking the front brake is easier going 80mph, and seating yourself firmly won't help. The only reason a bicycle flips is because the rider goes forward into the handlebars; without this momentum, the bicycle's weight distribution with the rider makes flipping a bike on level ground impossible, and difficult coming down hill (wear your helmet). The bike weighs about 6 pounds; the motorcycle weighs about 6 times what you do. The motorcycle will not only effectively ignore your weight (puny flesh sack), but also will have much more powerful brakes, much more momentum, and much more raw speed. In other news, you can't bunny hop a motorcycle by pulling up with your hands and legs.
