"Other people have started on 600s, 750s or 1000s and didn't get hurt. So why can't I?"

This is probably the number one reason that pops up. However, it isn't so much a reason as an observation. And it is a true one. Every year, lots of new riders bring home a brand new or used GSXR, CBR, ZXR, YZF or other kind of sportbike. And many of those riders do successfully manage to get through their learning process on these machines.

The purpose of a first ride more than any other is to get the risk of riding for the first year or two as low as possible. You want your margin of forgiveness in the bike to be as wide as possible. A 600 and bigger sportbike gives you very little of that. Yes, a 600 down low is a tame if sensitive machine. However, it takes very little twist on the throttle to induce a large jump in rpm's. A brief bump on a pothole with a death grip on the throttle can introduce a 4000rpm jump in the blink of an eye. In an experienced rider's hands, this is alarming but recoverable. A gentle rolloff or a little clutch feathering manages the surge nicely. In the hands of a newbie trying to figure out the best reaction to such a scare, a rapid closeoff or a panic brake is often the result and can get you into trouble very, very quickly.

Yes, a new rider can start on a 600cc sportbike. It is NOT RECOMMENDED! The reason this line of reasoning pops up so often is because everyone feels they are the exception rather than just another new rider. It makes sense. It's hard to think of oneself as just another face in the crowd.

In the end, to deal with this line of reasoning is going to involve the new rider, not the one giving the advice. No one can stop that person from going out and buying a high performance race bike as a first ride. And maybe they will succeed. Great! They were the exception.

What you don't hear about are the non-exceptional people. Very, very few new riders who start on 750s or 1000s come back to talk about their experiences if they aren't in the "I've had no problems" group. There have been many folks who admitted they got a XX sportbike to start on and indicated that it had been a less-than-ideal choice. This type of honesty is refreshing and it is very, very rare. I am grateful these riders stepped up.

Most of the time, we never learn the fate of those riders who start on sportbikes. Some make it and simply never bother to tell their tales except to friends. Some wind up scaring themselves so badly (by getting out of control or by actually dumping the bike and injuring themselves) that they sell off and never ride again. These types can be found. Just troll the ads for new supersports with one owner and low miles. The worst of this class of riders are the ones who become "born again safety advocates". These riders who scare themselves out of riding occasionally become preachers that tell anyone who will listen that "motorcycles are dangerous and should be banned". What they don't tell those they are preaching to is how they got that way. It's bad enough having to deal with the general public (who are at least honestly unaware of what riding is about) but a lot worse to be sabotaged from within by someone who did it to themselves and got in over their head.

Then there is the last group of these "started on a supersport motorcycle" riders that never tell us their tales. They never do because they can't. They made that one mistake, that one error that compounded into a tragedy of inexperience. They can never tell us what that error was so we can learn from it and maybe also tell us that they should have started on something smaller. They were successful right until the point their skills and luck ran out. This can happen to any of us on any bike. But, in the end, new riders on a powerful sportbike can be a recipe for disaster. And don't forget about the riders that screw up and are too embarrassed to tell anyone about it. Nobody wants to get the "I told you so" responses.

Be honest with yourself. Very honest. Take the advice and wisdom of others more experienced than you and consider what they are saying. They may have a point. But if you opt for that 600 and bigger sportbike, be assured you will still be accepted as a rider and still encouraged to act as safely as possible at all times.

What makes these bad bikes to start on?

Sportbikes are built as racing machines, pure and simple. They are built in response to guidelines laid down by racing bodies for a particular class and made to win races in that class. Ducati, for example, spends most of their existence building bikes to win races. Since 1950, Ducati was always a racing bike manufacturer first and their products reflected that philosophy. A by-product of winning races is the fact that people see those winning machines and want to ride them (if you're going to ride, you might as well ride the best as it goes). It didn't take the motorcycle manufacturers long to figure out that there was a market demand for these machines and reacted accordingly.

Sportbikes represent a technological arms race. This has really become apparent in the past 5-10 years where new models eclipse last years models with better performance and capability with each passing year. To compare a 1989 Honda CBR600F Hurricane (the original CBR) to a 2003 CBR600RR is pointless. There is no comparison except in the model designation showing a distant family relation. The new CBR is lighter by at least 50 pounds and packs 30 percent more power, handling and braking ability that makes the original CBR look like a ponderous dinosaur. But just because that original CBR dinosaur has been eclipsed doesn't make it any more tamable. If anything, older sportbikes are far more temperamental than the descendants.

Because sportbikes (and especially 600s since they compete in the most populous racing class out there) are designed first as racing machines, they are built with handling, acceleration and speed in mind. Not just one quality at the expense of others but all of them in abundance! Centralizing the mass of the bike at the center of gravity (CoG) gives the bike neutral stability. The high riding position and the perching of the rider over the CoG gives the bike the ability to flick over rapidly.

The steering geometry and short wheelbase of these bikes is designed to provide short and rapid directional changes. Combined with the higher CoG and mass centralization, the steering setup is what gives sportbikes their amazing turning ability.

And then there are the brakes. Braking technology has gotten progressively more potent over the past ten years. Even older sportbikes sport twin disc setups with two or four piston calipers designed to get these bikes down from 150mph to 60mph as quickly as possible. Current generation bikes are unreal. These brakes have grown to six piston calipers with massive discs whose sole job is to slow a 180mph missile down to corner speed in the shortest distance possible. If you ever watch racers, notice that they tend to only use two fingers to brake. They don't need anymore than that. The brakes are almost too powerful. And accidents happen on the track a lot due to bad or late braking.

All of these qualities produce an exquisite riding machine. The problem is, all of these qualities are designed to operate at extremes since it is under extreme conditions that these bikes are intended to operate. For the street, these capabilities are overkill. A hard squeeze of the front brake on the street can easily get a sportbike to lock its front wheel. Same applies to an over-aggressive stomp on the rear brake. No matter which way you slice it, highsides hurt.

The powerful engine can literally get you from 0 to 45mph in the blink of an eye in first gear. Come up one gear and you can be at 70mph with the slightest drop of your wrist. Add in one bump at speed without knowing what the throttle is going to do and suddenly you aren't at 70mph anymore. You're at 90+ mph and the bike is tickling its "sweet spot". At this speed, you better not panic. If you botch the slowdown from this error (either by a rapid rolloff or a shift), you can find yourself in serious trouble.

The handling capabilities of sportbikes actually make them wonderful machines to ride once you are used to thinking where you want to go. This actually gives them great beginner qualities (if on the extreme end). The downside is this perfect handling is slaved to amazing power on tap and the brakes that can back it off just as quickly.
