2012 HONDA VFR1200F,

;
• 237cc V4 Engine (Updated for 2012): Drawing on 30 years of V4 technology and racing success, Honda designers gave the VFR1200F what is surely the most advanced streetbike engine yet: a fuel-injected, liquid-cooled 1237cc, 76-degree, V4 brimming with low-end torque. Overall, it's more compact than the engine from the 781cc Interceptor. Updates for 2012 increase fuel economy and improves torque from 2000 to 4000 rpm.
• Compact Unicam Cylinder Head Design: Inspired by our championship-winning CRF motocross machines, we used Honda's patented Unicam technology to minimize cylinder head size, weight, and allows for a flatter combustion chamber for a quicker, more efficient burn while still allowing an impressive redline of 10,200 rpm.
• Differential Cylinder Bank Layout: Compact engine size was critical, so our engineers placed the VFR powerplant's V4 rear cylinders side by side but close together, while the front cylinders are more widely spaced. This makes the engine narrower near the rider's feet and allows the entire chassis and seating area to feature a distinctly narrowed profile.
• Slipper Clutch: We told you the VFR's parts manifest reads almost like that of a factory road racer. Example: A trick slipper clutch mechanism that moderates the effect of deceleration torque on the rear wheel, allowing engine braking to slow the bike without causing the rear tire to chatter.
• Low-Centerline Driveshaft: Take a close look at the VFR1200F and you'll see that the driveshaft joins the transmission far below the swingarm pivot (with most shaft-driven bikes the pivot is on the same plane). The result? The VFR1200F delivers a more neutral handling platform under both acceleration and deceleration. You get the best of both worlds: The virtually maintenance-free aspects of shaft final drive and the superior handling character that only a chain-drive system has previously been able to offer.
• Exhaust System: Take a look at the VFR1200F's exhaust system. Notice the two outlets in the silencer? The lower one is always open, while the upper outlet only opens at higher engine and vehicle speeds. That lets our engineers fine-tune the exhaust back pressure for optimal performance and sound. It's a great example of how technology can take something as simple as a muffler and use it to improve your riding experience.
