I have not read the test, but I wouldn't get too worked up over a magazine calling a bike old school. For most people, a two stroke is now old school. Fine by me. One of my favorite bikes in the world is about as old school as it gets. The Husky WR 250 has been slowly upgraded over the last two decades. It's a fantastic bike, and yet, that engine shares parts with the 1987 Cagiva it was derived from, right down to the engine cases. It's my opinion, that when you find a good platform and let it evolve over time, you get a more consistent product year to year that people can count on, it won't be a surprise grenade ever, and, while you lose the bold new bike craze that keeps you selling bikes to the vogue crowd, you get loyal customers that spread the word. Free advertising.
When you're a tiny company, that's a better marketing plan than spending cubic dollars reinventing the wheel every year.
