Review Motorbike Warehouse

The AJS NAC-12 is one of the most beautiful looking sports commuters on the market, the elegant lines, the underseat exhausts, black finish and excellent riding position all combine to make this an extremely attractive bike to won and run.

Powered by the AJS twin cylinder, liquid cooled SOHC four stroke balanced engine, the NAC 12 performs well; the twin discs at front and single disc rear means it stops well too, ably helped by the decent 90/90-18 tyre front and 130/90-15 rear. Weighing in at approximately 153Kg the NAC 12 is one of those bikes that feels and rides as a single entitty, more than the sum of its parts. And the 770 mm seat height makes it a little more accessible than some full size 125s.

Colour choice has expanded now to the startling and elegant white, or alternatively there is still the striking pillar-box red paint job or the ever popular gloss black, which really brings out the street fighter styling in the NAC.

This is a bike often bought as a commuter but almost always then enjoyed far more, not just a machine to get you from A to B quickly, cheaply and efficiently but as something that puts a broad grin on your face every time you throw your leg over it, you will be making up excuses for going out on it.
