BSA Gold Star launched

[PowerDubs_imp]

I doubt BSA's specs are real-world rear-wheel dyno, they may be starting at a deficit, (maybe 10%?). Hard to believe they would be in the same ballpark powerwise as BMW's Rotax-based 650, much less the KTM 690 Duke.

The weight is the killer though. It weighs as much as a W650 twin.

There has never been a motorcycle (or car) company in the world that advertises at real wheel hp.

All HP #'s are at the engine- not after drivetrain loss.

Heck- Remember old cars use to rate before any engine accessories were even take into consideration- AC, alternator, water pump, power steering, etc.

That being said- always take into consideration that a well breathing 4 valve cyl head engine can make 10hp per 100cc without sacrifice playing RPM tricks ...then deduct from there- for noise, emissions, fueling, packaging, and cost cuttings...
