A single-cylinder, DOHC, forward-canted motor allows for a straighter air intake channel and therefore better fueling from its fuel injection system, with a max claimed power of 55 hp.
The engine employs an unusual
reverse-rotating crankshaft, with the (cable-operated) clutch located
directly above the crankshaft, which reduces torque loads and allows
the use of a smaller and lighter clutch.
The swingarm is longer than on other
comparable bikes, and its pivot point is located in line with the
drive sprocket centre, so the tension of the drive chain is not
affected by compression and rebounding of the suspension.
A straight-tube (no bends?) frame is said to be
exceptionally rigid, and fully adjustable Marzocchi USD forks with
300 mm of travel and a fully adjustable Öhlins rear shock with
320 mm of travel should handle tough suspension duties.
The G450X weighs 120 kg with its 8.5
litre fuel tank full of gas, which is located under the seat for better mass centralization and to allow more room for the rider to move around.
No word yet on Canadian availability or pricing, although a BMW
spokesperson was "99% sure" that it will get here. Availability and
pricing should be announced towards the end of November.
