    How is possible to get that Acceleration?

    Dear Guys,

    How is possible to getr that acceleration and top speed with a 14/47 setup? O_O
    Even the RPM, how is possible that the bike stays at "normal" I guess RPM and reach over 100kmh in 4th gear while mine at around 90kmh sounds like it's going to destroy the world and cause an earthquake for how noisy it becomes
    Note that I have a 14/45, so techncially I should get less noise at same speed as him, but well... he seems to have like 14/37 maybe lol, not 47, how's that possible


    Also Using the TW200 speed calculator it seems that at 8500 rpm (so not the max which I believe is 9500) in 4th I should top out at 93kmh, so when I actually reach 90 I am at about 8400rpm so mean I can still push the bike? I am just worried about the sound because I don't have a damned rpm reader
    Still in the calculator if I set 47 as rear sprocket, and input as speed 110kmh (which he reached in 4th gear) he reach over 10k rpm, which is over redline... I still can't figure out how is that possible

    I want that, I absolutely want that

    You can rev them as high as you want. When the bike stops pulling, shift. He's got a cam in it too.

    1) put tw200 speedo on an xt350.
    2) film
    3) ....
    4) profit

    But seriously, you should invest the money in a tachometer to see what your engine is really doing. I found out with mine, in stock gearing, ~100kmh = 6900rpm-7200rpm in 5th gear. Prior to having the tach, I was convinced I was going to blow the thing up based on the sound.

    I would hope so. Bike wouldn't run so much without one.

    The easiest way, and the best way I think, to get good acceleration and lower rpm at speed is to get a different bike.

    Ok but that does not match with the speed calc
    4th gear, if I reach or try the same speed as the video the calc say i will be over the limit of 9500

    Am I missing something?

    If you are really interested in "speed" in the slightest, you will need a a different motorcycle.
    Then you will have "speed" but miss all the cool things a TW200 will actually do.

    There’s a half mile hill down to my house, the kind that if you take your foot of the gas in an automatic car, you keep accelerating (not by much, but you still pick up speed)

    I’ve come down that hill on a stock ’98 TW200 with a 14/49 set up, flat out, ignoring the noise and keeping it wide open. Partly because I wanted to see how fast it would go, partly to see if it would spontaneously disassemble (blow up), and because I knew I could coast home if it all went pear shaped

    (The following account is based on “indicated speed”, so figure in a maximum 10% error – body weight was 190 wet, knobblies front and rear set at 19 PSI – fresh gas, 5% Ethanol mix)

    60 mph was no problem, plenty left up the spout – 65 was as easy, so went for warp – at 68mph, some instability from the tire combination (TW34 rear, Hiedenau K60 front), not quite a “tank slapper”, but heading that way – so I backed off the throttle while I was ahead – but she would have gone through the 70mph barrier otherwise

    Now, you’re talking about a 14/47 set-up – so it should have a higher top-end performance, and if you then add road tires, not knobblies, you start to get faster acceleration (less tire drag) – and on those road tires, if you’re going for “speed”, you can up the pressures to 30 PSI, at which point it will really start to fly by comparison

    Engine mods take it even further (like some cam work)

    But then, you’re doing 70MPH on a bike with a short wheel base, no brakes that do anything over 40 MPH, and are so “off-plot” that you are effectively flying on a wing and a prayer

    Then you can take a youtube vid of yourself, and boast about it (while you’re still alive – this time)

    That’s not what the TW is about, and rather than thinking about “how did he do it”, you should be thinking about “why did he do it”

    Leave “Captain Testosterone” to his idiocy, or get an RD350 with knobblies ……..
