Not really a question but saw this older pic &

cannot help but be impressed with the simplicity & beauty

Honda NSR250 engine use to do just under 50hp

Even today some such as the KTM 250 Moto3 engine is quite nice. Just over 50hp

I think not quite as nice as the old 2 stroke twins but still nice + the FI etc.

Honda's 250 Moto3 not sure what the HP was but they were usually faster than

the KTM's in a straight line during 2014 season

Post some pics of what you think is beautiful examples of form/function if you like

Brake from the EBR 1190RS. A single front rotor turned inside out to reduce unsprung weight whilst stopping a world class 185 HP machine. Carbon fibre air rams to keep the caliper nice and cool.

Spidery die cast magnesium subframe. Weighs less than a kg (2 lbs). Hooks up to the main frame spars which contain the fuel in Erik Buell's quest for mass centralisation.

Cast aluminium hub-less wheels. Yet another way to reduce unsprung weight.

For somebody not often impressed by HD, Beull has always had some revolutionary ideas.

take your pick; the shoes, the bike or the undies!!

One of the nicest looking bike engines: MV Augusta 750 America

I actually like the RC166's pipes more than the engine.

You might not think much of this engine until you realize its a rotary.
