Cruisers account for more than 60 percent of the street bike market in the United States. Each year metric cruisers â cruisers built by company’s other than Harley-Davidson â account for an increasing portion of the cruiser market. Cruisers are about style, and the booming aftermarket is as focused on appearance as it is on performance. Every cruiser sold is modified, period. The changes might be purely cosmetic (such as the addition of chrome, custom paint, and touring equipment), or they might improve performance (aftermarket exhaust, engine mods, brake upgrades).
