    You need to GPS your speed.
    This forum has helped me get the most I can out of my Grom without going to a bbk and for that I'm thankful for all your inputs. You all helped me make it happen, for sure. My speed indicator is measure by how long does it take me to get to work When I rode a Hyabusa it was about an hour and when I ride my Grom it's about an hour
    BUCKNUT and solidjohnny like this.

    i'm just saying that you keep quoting speeds, but aren't taking errors into account. the error you are proposing is only gearing error, not factory speedo error (which can be significant). so while from factory the odometer is correct, the speedo is not. this is intentional as a speedo reading a little bit optimistic is much less a liability than one reading incorrectly the other way.

    Error on the error will always be. I'm quoting the speeds on my speedometer with the 1 and only 1 change being a +2T on the rear sprocket. Read into it whatever you want.

    And the +500 rpm increase to the limiter

    And the removal of the oil spinner

    And the removal of the CA smog box and ecu setting

    And the heavy duty drive chain

    And the speed screen! lol... Sorry bros, you may be too heavy for a Grom.

    And the air box removal replaced with a pod filter over a radiator hose clamped to the throttle body

    With a hole drilled into it for the air intake temp sensor

    And the crank case breather hose routed to an open air filter.

    I'm probably not leaving out one more thing. I got them all... On the Grom If you can't do it go bbk.

    if you're looking for comparisons, the only way is with ACTUAL speed. not inferred speed.

    We're talking 2 mph at most? That's actually insignificant.

    In my last speed test I hit 74 mph and previously I hit 76 mph... why is that so hard for you to believe?

    on most bikes the factory speedo error is >5%. it gets worse as your tire wears


    anyway, you can keep posting your speedometer. but nobody else trusts it, you'll see this in one of the millions of threads just like yours.

    An honest commentary and experience can not be trusted? I trust them when I see them. I'll pontificate for you; I love your bait... I've gone 108 mph on my Drz400s. My '96 ZX-6E cruised at 135 mph chompin at the bit. My '95 ZX-6R did 140 mph when I backed off for the nut job in the porsche. My '85 FZ750 did 135 mph and started to wobble. My XN-85 turbo cruised all night at over 120 mph. My '86 XR 250 did over 70 mph. My 1200R Roadster will cruise at 114 mph before the engine cut at 115 mph. My '97 CBR600F3 has no speed limit and the same for my '98 ZX-6E. My '06 636 is in no doubt faster than them all. And my Grom rips all day at over 70 mph, bitch!
