The Sportster plant in York, Pennsylvania has been over 50% contract/temporary part-time worker and nearly 70% capacity since that Wandell wanker CEO sold MV back to the Castigliones and shuttered Buell. This year, they also did a round of layoffs and salary reductions due to decreased demand. They do other things besides build Sportys like making tanks, fenders and chassis.
But not even attempting to meet Euro5, which isn't much different than meeting California's CARB requirement, was simply putting another nail in the coffin. In the USA, the most bikes sold are the baggers and other touring lines. Softtails are next. Sportsters are a small market here. And hardly anyone here buys the XG Street models. Most are listed as sold by the MoCo only because it is the dealer who bought them.
I wouldn't be surprised to see the Sporty line fade away or at best continue on as a combination of XL and XG, much like how they combined the Dyna and Softtail line because the Dynas were floundering. But if they don't make the XG a much, much better bike, then it will surely disappear completely. No one here wants the XG and the flat track version isn't a winner nor does it resemble what you can buy on the floor. The Indian FT1200 and 750 flat track version are killing Sportys at the till and the races.
