This manageable powerplant offers superb roll-on response and enables the ER-6n to fluently The non-intimidating twin-cylinder appeals to riders with its excellent mid-range and plenty of character to thrill more advanced riders. The clean, size-efficient engine delivers good fuel economy and also meets stringent emission regulations, thanks to its precise fuel-injection and a three-way catalyzer system. Its coolant is routed to the cylinder and head through the engine cases, reducing the number of hoses and simplifying the cooling system.
Its fuel injection settings grant the engine plenty of bottom-end torque and smooth low-mid rpm response. The key to the ER-6n’s slender size is its compact liquid-cooled, fuel-injected, DOHC 8-valve 649cc parallel-twin engine, which permits the use of a narrow, lightweight frame. And did we mention deleting the fairing also brings the price down substantially? Otherwise, the ER-6n packs all the hardware and handling that’s made it and its Ninja 650R brother such media darlings. This one’s for riders who love the feel of being in the wind — a particularly good thing if you mostly ride where the weather’s hot.

The ER-6n simply leaves a little more of that torquey, rev-happy 650 twin’s innovative inner beauty out where you can see it, revealing this soulful machine’s mechanical purity of purpose. But nearly all riders agree Kawasaki’s Ninja 650R is a great, fun-to-ride middleweight motorcycle. Some riders like a fully faired sportbike, some don’t.
