This is the motorcycle that has Bajaj and TVS all stirred up. Sadly, it isn't because the damn thing's so good looking. Hmph.
The nub of the matter is that the TVS has two spark plugs and a third valve – an inlet that opens later, sort of like VTEC. No all that's wrong. What happens is that TVS' carburettor opens into two vertically stacked manifolds that lead to the two intake valves, one each. As the carburettor slide rises on throttle application, the fuel-air mix first begins to travel down the lower one, the 'swirl port' as TVS calls it. This port is designed to operate with maximum swirl, generating maximum possible turbulence to allow the engine to offer great economy and torque. As the revs (and the slide) continue to rise, the carburettor begins to feed the motor through the other manifold, the 'power port'. This port is straigher compared to the curvy swirl port, and it's job in life is to flow more mixture. At high revs, this allows the engine to breathe deeper and make more power.
I haven't had any saddle time, but am told that the torque levels are admirable. In many respects, this might be the best looking 125 on the market soon. Launch is expected by November. The rest of the text is from TVS. And the photos are all from here.
The all new 125 cc FLAMERelated links
The all-new 4 Stroke, 4 geared 125cc FLAME is the most innovatively designed offering from TVS designed to win over discerning customers with its futuristic styling and technology. The 3-Valve Engine comes with Controlled Combustion Variable Timing Intelligent (CC-VTi) technology.
The styling of Flame is inspired by the Delta Wing design found in the latest fighter jets. Called “DeltaEdge”, it gives the bike a unique style while giving it superior aerodynamics. The FLAME boasts of several style statements including, DeltaEdge Headlamps, Sporty DeltaEdge Exhaust, Embedded DeltaEdge Trafficators, LCD Digital Speedometer and a Dual Lens Tail Lamp.
Developed by world class R&D at TVS MOTOR, in collaboration with AVL, Austria, the CC-VTi technology features 2 different intake ports called Swirl port & Power port.
Swirl port creates swirl motion of air-fuel mixture in the combustion chamber. This Swirl motion helps in efficient combustion of lean air-fuel mixture thus giving highest fuel economy in its class. Power Port gives high flow rate, which helps in delivering high power. The engine packs in 10.5 bhp @ 8250rpm
The 125cc FLAME promises to be the best looker in its segment. Keen attention to detail, marks this new offering. DeltaEdge styling coupled with snazzy dual tone graphics translates into an amazing road presence. With the revolutionary new CC-VTi technology, the 125 cc FLAME successfully provides the advantage of power, mileage and stunning looks.
