History[edit | edit source]
In July 2007, Buell announced the 1125R, a sportbike which departed from Buell's history of using Harley-Davidson Sportster based middle weight powertrains and tapping into the XBRR racing bike learnings. The Rotax powertrains uses four valves per cylinder, dual over-head cam, liquid-cooled 72 degree V-Twin displacing 1,125 cc and producing 146hp. It produces 83ft-lbs of peak torque but varies less than 6ft-lbs of torque from 3,000 to 10,500 rpm. There is a vacuum assist slipper clutch to give predictable drive performance in hard cornering and deceleration and a 6-speed transmission.
The engine was developed by Rotax and built in Austria.[2] The design had significant Buell input, and was funded through Buell's cashflow, likely for 15–20% of the V-Rod engine development cost.[2]
The 1125R did not have a full fairing, as that would have put it in the same class as Japanese sportbikes.[2] Erik Buell agonized over this, saying "it's not about listening to the voice of the customer."[2] Cycle World said the 1125R was "a bit of an oddity."[2] The bike was initially released with a crude spark map, leading to criticism of the bike at low speeds.[2] The Rotax engine also ended up costing significantly more by production time due to fluctuation in exchange rates.[2]
Engine[edit | edit source]
The engine was a liquid cooled liquid-cooled, four-stroke, 72-degree V-Twin. A 104.1mm bore x 104.1mm stroke result in a displacement of just 1125.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive[edit | edit source]
The bike has a 6-speed, manual transmission. Power was moderated via the slipper clutch.
Chassis[edit | edit source]
It came with a 120/70 ZR17 front tire and a 180/55 ZR17 rear tire. Stopping was achieved via single 375mm disc, 6-piston caliper, ZTL2-type in the front and a single 240mm disc, 2-piston caliper in the rear. The front suspension was a 47mm Showa upside-down fork while the rear was equipped with a Showa fully-adjustable shock absorber. The 1125R was fitted with a 5.28 Gallon (20.00 Liters) fuel tank. The bike weighed just 375.01 pounds (170.1 Kg). The wheelbase was 54.49 inches (1384 mm) long.
