2018 TVS Apache RR310 Production Factory – Video
The Apache RR 310 has been designed extensively to provide top-notch aerodynamic performance. It has been wind-tunnel tested in India for over 300 hours, resulting in slippery bodywork with a best-in-class coefficient of drag as per TVS’ claims. The gill vents on the fairing channel hot air away from the engine and TVS has also designed a deflector cowl (patent pending) that diverts engine heat downwards and away from the rider.
While the windscreen isn’t adjustable, it is, by default, accommodating enough to allow even tall riders a full racing crouch. Another notable touch is the panel gap consistency, which is a quality-control measure but also aids the RR’s aerodynamic performance.
The 312.2cc, liquid-cooled, single-cylinder engine has been jointly developed by BMW Motorrad and TVS and is common to, both, the BMW G 310 R and the Apache RR 310. The DOHC motor produces 34hp at 9,700 rpm and 27.3Nm of torque at 7,700 rpm, and is reverse inclined (tilts backwards), with the exhaust port emerging from the rear as well. This helps position the engine further ahead allowing for a longer swingarm, while keeping the wheelbase short, which aids stability and handling progression.
The position of the engine helps it comply with emission norms since it makes the required exhaust length shorter, helping the catalytic converter heat up faster. Thanks to the cylinder head featuring a down draft port with a button tappet arrangement, this engine benefits from an 8 per cent increase in volumetric efficiency. This essentially translates to better intake characteristics and optimum use of the air-fuel mixture available within the cylinder. Additionally, the crankcase is a horizontally split unit and the engine is mated to a six-speed gearbox, which is slick and encouraging of quick gearshifts.
