2014 Yamaha Roadliner S For those who think big. Our biggest V-twin is also our boldest, with a highly advanced fuel injected engine producing peak torque at only 2250 rpm. And an aluminum frame for the kind of solid, precise handling nothing else in its class can touch. The 2014 Yamaha Roadliner S gets chrome switchgear, front brake and clutch master cylinders and levers, belt guard, fork and fork covers, handlebar clamps, shifter, front pully cover, various engine covers, rear fender stay and polished wheels.
