R15 V3 is a mad machine!!! Love it

[@operatora588]

So... This is just like VTEC.

What's vtec?! An technology come from the brand that well known in South East Asia only?! Hahaha :)))

Not vtec but vvt

Basically, this thing work like VTEC but changed little bit by Yamaha. Ihope I get it right

[@jirafisher1911]

VVA narrow - wide timing cam step ,but VTEC low - high lift cam step.

[@rizkiekosaputro5831]

Mungkin ini alasan Yamaha tidak mau membuat mesin DOHC . Tapi lebih memilih mengembangkan mesin SOHC

[@vitomf2571]

Yoi,,tapi minus ditopspeed,,kalo dohc minus dibawahan akselerasi nya,,terus lebih hemat ini dibanding dohc karna dirpm bawah pembuangan klep dikit

[@boxednerd]

VVT, VVA, VTEC, etc. All started with the Cadillac back in 1903, if I'm not mistaken. Porsche did it back in the late 50s. Torazza did it in the late 60s. Alfa Romeo did it in the early 80s. Honda did it shortly after Alfa Romeo. Most car and motorcycle companies have their own versions and they all just copy each other. Not a new concept but it is amazing never the less. Motorcycles had it back in the day but decided to phase out the system because the weight penalty of having a variable valve system was too much for it to be useful. I know there are holes in my data but I'm just going by memory here.

is the VVA actuated by a hydraulic pin like in honda's vtec?

Love the VVA system

[@tiagofigueiredo2529]

Thank Honda for that 😅👍 VTEC, VTEC-E, i-VTEC and 3 Stage VTEC 💪

[@reoglah]

@@tiagofigueiredo2529 yess thanks for honda, but their low to mid cc bike didn't use that which is a shame

[@corolla9545]

Its funny to think that this VVA technology is copied from Honda's VTEC technology, and yet Honda did not adapt this technology in their motorcycles especially scooters like the PCX, Click and Airblade.

[@m.firdausrosni897]

Actually honda made for big bike.. The only bikes have vtec is cb 400 hyper vtec, vfr 800, Honda Integra 700 and a few bike.. The vtec on bike is only for fuel efficiency & power for hi end.. But this system is applied on 2005 onward.. The vva just only copy & paste.. And also, vvt is different thing from vtec.. Don't get you wrong

[@reoglah]

@@m.firdausrosni897 yeah but honda didn't use that on thier mid end bike which is a miss opportunity there

[@akmrp7423]

[@rachmatzulfiqar]

@@reoglah not missed opportunity, its just a simple ignorance breed by arrogance, Honda knows that no matter how little their effort to develop a motorcycle engine, folks are gonna buy it anyways over other competitor, Honda is borderline monopoly in terms of market share in Asia.

[@ArHahn]

mostly people didnt know, the First is YPVS technology from yamaha it self, then other companies copied yamaha technology.

[@Sam-to1zg]

I assume you will never reply me but lets hope for it. My question is Is cylinder 1PA-E1311-00 still uses DiaSil technology ?

[@Sam-to1zg]

What is the difference between these Piston Rings 3C1-E1603-00 3C1-11603-00

[@hendycd]

I mean it's only applied on the intake. So there's no difference about the sound, unlike Honda's VTEC on bike like CB400F.

[@rayking5157]

at least it gives more power and efficiency on high rpm

[@hendycd]

Vtec for honda, VVT for toyota, VVA for yamaha

[@shhhhhh86]

Vtc Nissan, Campro CPS Proton

[@hochhaul]

Toyota VVT is not the same as Vtec. VVT rotates the cam relative to the crankshaft. That changes the timing of intake valves opening and closing relative to the piston's stroke.

Ahhh, the good ol' VTEC system created by HONDA in the 80's and used till this days 😅 VTEC, VTEC-E, i-VTEC and 3 Stage VTEC 👍 Used both in motorcycles and cars, mostly cars. This was revolutionary 30 years ago, now Yamaha is using the technology developed by other company years ago and stating it's "a new invention" or "new technology". Only fools go with it 🤷‍♂️😅 Pretty cool though 👍

[@subhajit1128]

It's very useful if used instead of DOHC. VVA in SOCH gives very pretty top end. Clever move by yamaha.

[@Vtrontv]

@@subhajit1128 He is not that smart to understand the reality. If you talk about steering wheel he will say was invented years before but only fools will buy it 🤷‍♂️😅

the thing is that it's for motorcycle, not cars. even 125cc scooter getting vva by yamaha. where's honda?

'Vtec' just trademark...before that 'vtec' used in train engine...long2 time ago...

[@tiagofigueiredo2529]

@@jiwaelectro No, before VTEC, VVT/VVTL systems existed and were used in vapor locomotives engines, before 20th century, other car manufacturers since then used some kind of VVT/VVTL systems but VTEC and the way it works was developed and perfected by Honda and that system wasn't developed by anyone before. There have been a lot of other systems, each one is unique. Yamaha and Toyota have copied the VTEC system developed by Honda. 🤷‍♂️
