Just months after announcing it intended to offer a range of cafe racers based around the Buell Blast's single-cylinder engine, Mac Motorcycles was blindsided by Harley's declaration that large-scale production of the Blast would cease. Left without a cheap supply of air-cooled singles, Mac is considering the liquid-cooled engine from the Yamaha XT660Z. That would mean more power if less pure looks. Good idea?

The Blast's carbureted 492cc engine makes 34bhp at 6,500rpm and 30lb/ft
of torque at 3,200rpm. In comparison, the 660cc fuel-injected Yamaha
engine makes 48bhp at 6,000rpm and 43lb/ft of torque. Like the Harley
unit, reliability is almost a given, upgrades are plenty, repair is
cheap and sources for parts are widespread. Mac says the swap wouldn't
have a noticeable impact on the end price and we wouldn't expect much
of a weigh difference, despite the addition of a radiator.

A more significant concern of Mac's appears to be the looks. These
details and this image were emailed out to potential customers to gauge
their reaction to the change. While purists will undoubtedly bemoan the
lack of fins and the addition of all sorts of pipes and other addenda,
we actually prefer the way the Yamaha engine looks in the frame. It
adds a welcome dose of the contemporary to this Mac Spud's classic
looks, something that could give it added appeal to buyers in their
twenties and thirties. That could be a very good thing. As
Harley-Davidson is finding out, Baby Boomers stopped floating the
motorcycling industry about this time last year.

Head on over to the Mac Motorcycles website and tell them what you think.
