    I have seen this information somewhere but I can’t remember where exactly.

    What is the maximum speed you can get at each gear? ZL900 of course. ;)

    :hello: Go to the artical thread. Cycle & Cycle World has the stats on top speed in each gear. My ZL 1000 topped out at 145 MPH.

    With the 170/80-15 rear tire that most run, it seems to me that the Speedo error would be effectively corrected.

    IMO the prob is the speedo showing too much like they all do, not more or less rpm depending on tire size. The faster the wronger, so GPS or digital one programmed w/ right factor.

    Th rear tire has nothing to do with the MPH indicated. That is all done by the front tire.

    Talking about speedomeeter error, I did a test yesterday with my GPS. When the speedo is at 100km/h, I'm actually going 92-93 km/h.

    For the record, the Jap bike manufacturers have always lied about speed. From the factory speedos are set up to read much higher than the actual speed. Probably helps sell bikes. The error is somewhere in the neighborhood of 10%+. Hate to burst some of you guys' bubbles, but your bikes aren't nearly as fast as you think they are. An easy way to find out approx how far off your is, is take it out on the highway and peg it at 60 and time from mile marker to mile marker. If accurate it will take exactly 60 secs to go 1 mile. 60mph = 1 mile per minute = 1 mile per 60 seconds. I do this with all my vehicles. My Chevy truck has always read a bit high which is fine by me. Probably has saved me a ticket or two.

    :hello: It's kind of hard to do the mile marker thing while riding a bike. How do you know if the hung over mile marker puter in the ground guy put it in the right place. :laughing7:. The GPS is easier.

    As a past compeditor in top speed events, We have tested the speedos at silly speeds.
    First. Legally speedos only need to realatively accurate at legal speeds...How would anyone ever know their speedo is wrong at 90mph 'coz we don't break the law.:laugh:
    Second. The old analogue speedos are by run friction or magnets so almost inmpossible to calibrate to to be accurate even over a short part of the range.
    Third. I took my ZX12R ( with big pistons, cams etc. ) to 203.5MPH verified. GPS showed 203.2. Digital speedo showed 219. (10% error).
    It showed roughly 10% error over the whole range....i.e 27-28 at 30 etc.
    So even digital ones are set by the manufacturer to have a saftey buffer.

    Interesting point, but not an issue. Just do it more than once, eh? Actually those damn things seem to be very accurate. When doing this, there is no reason not to repeat several times and those times have always been exactly the same, so I'd say your point it moot. BTW we all don't have GPS capabilities you know. If you're referring to using your cell phone, sounds like a bad idea to mess with your phone while riding. A glance at your watch seems safer as well as simpler. I like the old adage: KISS

    "If you're referring to using your cell phone"

    Just set your app and it'll record your speed, including max speed. So if your needle hit 70 and never went over, then your GPS app will show how close to 70 you were.
    All done after your ride while sitting in your armchair.
