There are a couple ways to approach the problem.
If off-the-rack, relatively inexpensive products like Joe Rocket, Spidi, Teknic, etc. both fit and appeal to your sense of aesthetics, by all means go for it. Plenty of guys have great luck with such stuff for street riding and the occasional track day. I owned an inexpensive suit that worked great for street riding, back in 1994. This forum’s filled with such riders and that’s as good a reason as any to try them.
If you’re outside the norm in terms of height and/or weight, you may end up with a custom suit. They’re nice, fit very well, but tend to be expensive. There are ways to do these on the cheap as well, however. Do a little research in other forums catering to a slightly different demographic, see what you find.
If however you’re a thoughtful consumer, concerned about placing your hide in jeopardy on a race track, ask yourself this: what do riders who are NOT paid big sponsorship bucks ride on the track? The answer may be found in the pit area of just about any roadracing club in the U.S. (and elsewhere, presumably).
Looking around a little, you’ll find a lot of scuffed leathers with names like Syed, Vanson, and Z Custom. There’ll be a few Kushitani, Tiger Angel, and custom Dainese suits, too. Yah, some of the others might also be there, but ask how they crash and consider the answers. If you don’t like the answers, investigate further and look for consistency.
Almost all leathers work great in a crash once. My inexpensive suit worked just fine in a 70 mph Sears Point Turn 5 get-off in 1996. All crashes are different, naturally, but take a look at the seams, zippers, leather abrasion, etc: some crash better than others. Maybe you won’t mind throwing out or selling your leathers after one big crash; I sold mine to some kid for $150. Again, it depends on your mindset and how you intend to use the products.
I’d not hesitate to buy most common brands of leathers for street riding, and in fact own some Joe Rocket and similar gear. On the track, however, why take the chance? Your choice; know thyself.
