My experience, working for 5 years as an on-track instructor for one of the largest track-day providers in California, suggests that the opposite is true. I think that you, and everyone else who trots out this ridiculous adage, are confusing racing with street riding. If you want to be fast on the racetrack, then it can help to start on a smaller-displacement bike. Just keep in mind that when racers say "small displacement" they usually mean 125cc GP bikes which have modern frames, slick tires, great suspension and great brakes. Every n00b I've seen riding a Ninja 250 at a trackday has ended up struggling to make progress. And who can blame them? The bike has a crappy frame, crappy tires, crappy brakes, and a crappy engine. I've been riding for 20 years and wouldn't want to trust that bike, so I can't imagine how a newbie would ever get comfortable...
I've ridden the Ninja 250 on road and track and I've also ridden the Honda Rebel 250 on the street. If you're certain you will never need to ride on the freeway, then they're mediocre choices for a beginner bike. If you'll ever ride on the freeway (and, let's face it, most of us don't have the patience to ride everywhere on city streets) then these bikes are awful. On the Bay Area's fast moving freeways, these bikes just don't have enough top-end acceleration. Just look at the 1/4-mile times for these bikes: the Rebel does the quarter in 17.86 seconds with a trap speed of 68mph and the Ninja takes 15.58 seconds with a trap speed of 82mph. This is the sort of performance than makes every freeway on-ramp into a sphincter-tightening experience! Which is why buying something like a Ninja 650, SV650 or FZ-07 makes much more sense: these bikes have enough horsepower to take you anywhere in the Bay Area, yet not so much power that they're likely to overwhelm a new rider. They'll also offer better tire options, improved suspension, and better brakes which all serve to improve rider confidence.
BTW, I'd love to hear a list of riding skills that are easier to learn on a Ninja 250 than they are on a Ninja 650...
Guess you missed the bit where I said 340lbs being too much for a first bike, eh? You do realize that an N250 is well over 340lbs, right? If you are going to respond with
out of context conclusions doesn't that just invalidate what you are saying? Still even in your own text you are agreeing that smaller bikes make for better learning.
Additionally, where have I said that the N250 is a good starter bike, or even a good bike? I regularly call it a pig. I've even been published in City Bike with my feelings that the N250 makes for a poor first bike. Shit the damn thing weighs the same as my 899. I also don't like the Rebel--mostly because of the foot placement, but for other reasons too (with regards to a first bike). Its low seat hight though sells a lot of bikes to vertically challenged riders--that's something that should be accounted for by the marketing staff when designing (some) bikes for new riders.
You realize that freeways are far safer than city streets, right? Everyone is going the same direction, you almost never have to deal with driveways or cross traffic, everyone is going about the same speed, etc. In my experience, you're far more likely to have problems on city streets. Given the number of people I see running red lights or turning left directly into the path of motorcyclists, I'd much rather ride on the freeway than most city streets. Of course deserted mountain roads are my favorite place to ride... but getting to most of them involves freeway riding.
Have you been following
this thread? It's in direct conflict with your conclusions. The reason being that what you are doing is confusing frequency with severity. I made clear references above that the freeway should not be employed by new riders because the incidences are quite likely to be catastrophic, and you can't learn from being dead. New riders don't have the tools to deal with issues that arise on the freeway. Those have to be developed, and you don't get taught any of that in the CMSP or MSF training. It's a huge difference from the parking lot on which they noodle around. You'd have to have a pretty hard cranium not to get that concept.
And are those people riding their 50cc scooters on a fast-moving freeways filled with aggressive assholes who routinely drive at 20+mph faster that the posted speed limit? Or are they riding in crowded urban environments where everyone else is also on a 50cc scooter?
Again a new rider for VERY OBVIOUS REASONS should not be on the freeway. Additionally there are plenty of non-scooter motos in the 50cc and up classes. Ones with decent brakes, suspension, design, etc. Most of them are not sold in the States currently, but that has a lot more to do with the fact that many people that buy bikes in the States are compensating. Hell Suzuki should just rename the GSXR the Compensator.
The riding community is aging out. The average age of a first time BMW buyer is 57 years old! That's the average. Meaning that there are some pretty old fucks buying a BMW for the first time. Moto sales are down because we are not properly cultivating new riders. To do that we need small bikes. Bikes that will allow the riders to develop in to good riders. Small bikes will do that faster and better than any other bikes out there.
As for ABS. It's still a fairly recent development in bikes. Many of the newer bikes, even the small ones, now have options for ABS. As for cornering ABS many of the high end bikes don't even have it, so to assert that a small bike without it is lacking in the way that you have in this thread is really disingenuous. It would have been a lot better had you explained what it is, and why it would be nice to see it implemented across the line of motos, rather than just on the high end bikes.
From memory cornering ABS only came out in 2013 on bikes, and there are still very few that have it today--usually the top of the line bikes. But like most tech it eventually shows up down the line. Especially on Euro bikes where in 2005 the 50cc bikes were showing up with inverted forks, radial brakes, braided lines, etc. Things still lacking on a lot of Hondas even in 2017.
There are some pretty nice starter bikes out there for sale. We as a community need to advocate that they be sold to new riders in our country, and we need to support those riders starting out with a proper non-freeway legal bike. All this rubbish about starting on a 650 just causes people with interest to quit at the first sign of issues. That doesn't help or promote our community. All you have to do is look at the numbers to see where it's going. This fucked up compensating mindset had done its damage long enough. If you love this sport it behooves you to wake up, and start fostering a responsible introduction to motos.
