Buell 1125R Review

June 28, 2016


Buell 1125R is the manufacturer’s first water-cooled engine bike and was released in much hope. Buell, being one of the largest makers of sport-oriented bikes in America, it designed premium class 1125R, featuring Buell’s signature engineering traits, like Zero torsion load, belt final-drive, and single 8-piston caliper.

Engine Specs


The motorbike is equipped with a Helicon 1125cc V-Twin engine, featuring four-valve cylinder heads and double overhead camshafts. This modern technologically proved design benefits from liquid cooling. Buell along with its Austrian partner Rotax designed this sports bike engine, which generates 146hp. Hydraulic Vacuum Assist clutch and 6-speed transmission completes the power-train.

Power delivery and gearbox are peachy and this bike is a major move to step away from Harley Davidson in terms of water-cooled lump. The 146hp at 10,000rpm sounds powerful.


The swing arm and thicker twin-spar frame have been built out of aluminum; the suspension in the form of Showa rear shock and Showa inverted fork links directly between swing arm and frame, without any leakage. The engine has been revised slightly and other minor modifications include calibration setting and color.


The engine designed by Rotax has good reputation for reliability; the liquid cooled motor matches the chassis and other features. The bike is very flexible and tractable from top gear. It vibrates at 4000 rpm and you can ride it just on a single gear, if you want and the bike behaves well on track or on the road. If you have used British, Italian, or Japanese gearboxes, then you may find this one a little heavy, but gear changing isn’t a problem with Buell.

The new eight-pot caliper weighs less than typical dual-disc system, hauling the complete 170kilo bike up nicely indeed. Out on the road, it proves like a real hit, as brakes and suspension work excellently brilliant.

In a Nutshell

1125R is both defined and unique; it’s a significant step for the manufacturer. The flawless gem is practical on road as well as track, thanks to the better and rewarding engine. It has a different proposition over other models and with contemporary sports models getting more uncomfortable and smaller, this machine is a real breath of fresh air.
