2017年1月30日 · Variable valve timing (VVT) falls firmly into the second camp. As a technology, it’s been around for decades but while car makers have long since embraced it, motorcycle manufacturers have shunned it. But, just as they’ve been obliged to take on ABS, the tightening clench of emissions regulations will soon force companies to look again at VVT.

Variable Valve Timing (VVT) has revolutionized motorcycle engines by harmonizing low and high RPM performance. This advanced mechanism balances power and efficiency, adapting to various riding needs. Let’s dive into how VVT transforms modern motorcycles.

2024年3月27日 · Small variable valve timing twin-cylinder engine emerges in patent. Suzuki is working on a new VVT design for its small-displacement engines.

2023年3月16日 · With emissions restrictions getting tighter and tighter, VVT could help its air-cooled V-Twins remain compliant for a few more years. A new VVT system would also explain one of the questions we had about the engine’s displacement.

2015年7月14日 · The VVT varies the timing of opening and closing of valves for multiple engine speeds. At high speed, the Inlet valves open quite earlier so that more air-fuel mixture or ‘charge’ enters the cylinders. This helps to increase engine’s breathing which also improves its ‘volumetric efficiency’ to a large extent. How VVT Works?

2023年8月22日 · Variable valve timing will help the Suzuki Hayabusa meet future emission regulations, and also help improve performance, fuel consumption and torque spread.

2017年1月3日 · What Is Variable Valve Timing (VVT)? The next frontier in motorcycle engine technology. Ducati’s “valve timing adjusters” reside inside the cam pulleys and continuously …

2023年9月18日 · Read about Suzuki's new VVT system destined for a future version of the Hayabusa with even more power that will still make it past emissions regs here.

2023年8月21日 · Several newly published patent documents have emerged showing a version of Suzuki ’s Hayabusa fitted with variable valve timing, a system that could help add even more performance while ensuring...

Yamaha’s VVA arrangement has finally been applied to a ‘proper’ bike – the YZF-R125 – and BMW has added variable valve timing and lift to both its boxer-engined R 1250 range and to the all-new S 1000 RR superbike.
