Buell is doomed...
The problem is, all the new ones do is RESTORE the engine stroke, as the XB9R/S engine is the short-stroke blast-version of the sportster-engine design.
But who CARES!?! The engine is one of those abominations which should have been shot 10 years ago: You don't make a real sportbike, or even a good pseudo-sportbike, out of that cruddy, unbalanced, overweight sportster POS!!!
Even HD doesn't use the engine except in the bargan-basement sportsters. The only reason for the funky (and expensive) gas in frame, oil in swingarm, and other funkyness is simply because the bloated sportster engine needs a MASSIVE frame, a gigantic airbox, and a separate oil tank.
Only the Buell "faithful" would ever get one, the same market which have gotten such dismal results in the past: 1.6% of HD's gross revenue ($66 million), a whopping ~10,000 bikes a year (including the wretched Be-last, grossing ~$6.6k/bike,[1]) and the same basic numbers for the past several years.
It always suprises me that HD keeps buell alive. There must be some nasty clauses in the origional buyout agreement which keeps them from closing the line and producing more big bikes, after all, the cost of making a Buell is about the same as making an UltraWideBody747ClassicElectraglide, which can make $5k-10k more for HD, with the same employees and a retooled assembly line.
[1] Compare this with the HD line, which sells $3.1B gross, on 260k bikes, so about ~$12k/bike. So the HD line gets nearly double the revenue/bike! ANd HD has the sportsters bumping down the value/bike, at ~50k/year sales.
