Yes but beans out of a corner up to specific speed or gently feeding her up to that speed affects it...There are more aspects, as you would well know.

Indeed... But to make such a noted difference doing pretty much the same route at pretty much the same speed surely cant be entirely down to just the rider? Ah well... not to worry. We can at least say the VTEC doesnt help by much if it does on fuel economy? |

And no reason why not, just ****ing and dordling in the wrong gears can hamper your economy. |

Not quite. VTEC = variable valve number. Normally Cams are setup to give max flow at a set RPM. If you have variable valve timing it means that you can set the CAMs most or maybe even all RPM's as it changes the timing and overlap accross the rev's to give Max flow at all revs. VTEC uses 2 valves at low RPM and 4 at high. Pretty different. ![]() |

![]() VTEC as a technology introduced by Honda is Variable Valve Timing Electronic Control. Most VTEC systems in Honda engines combine altered lift/valve dwell with the ability to step 'on or off' cams, which can be used to open more or fewer valves as well. There's some argument as to whether the VTEC implementation on Honda motorcycle engines 'counts' as really belonging to Honda's VTEC 'family', as it works in a slightly different way to the car engines' system. Strictly speaking, the VFR's VTEC system doesn't quite work on the basis of 2 or 4 valves - the 2nd pair of valves are usually opening to some extent even before the VTEC 'step', just not very much. Once the oil-pressure actuated cam comes 'on' they just open more. Even if this wasn't the case, one can argue that this is the very definition of variable timing - the variability being, in this case, from 0 degrees open to X degrees open. |
