    Probably what ever stock gearing is would be fine,or for a quick fix a bigger front sprocket if it will fit.

    I had a new KDX-200 in 1986,first year with disc ft brake Im pretty sure,and some other updates.
    At 6' tall I didnt really fit too good on it but it was a good little trailbike.

    Joined the 200(200ish)cc club yesterday. '95 KDX200, 220 cylinder, RB Designs head and carb, YZ forks, FMF exhaust. My dad built this as a second bike over the past few years but it wasn't getting much use so I snagged it for myself. First "modern" bike for me in a long time image_50330.jpg

    Here my 200cc Yamaha TY a contemporary MAJESTY rebuild with the frame of the British John Shirt, this frame was called schoolboy frame, especially for the 175cc which was too available as a 200cc variant.
    To get 200cc the standard sleeve of the 175cc cylinder was literary drilled up to a bigger diameter of 60m, with the conrod of the 175cc YZ model you had a lighter but stronger conrod to compensate a bit the additional piston mass.

    All in all a nice ride just 76kg in weight (152 pounds) and very strong, the fork is from a 250 TY Mono Trials bike, the swing arm lengthened and as rear suspension British Rockshox, for better aspiratoon a bigger airbox, a 16mm Dell'Orto VHAST, the reeds of the 250cc TY twinshock and a bigger exhaust system, gas tank is genuine TY Majesty made out of aluminium.

    Thank You, it was a long ongoing project I started "collecting" items 10 years ago with:
    2011: getting the frame,
    2011: found a 175 cylinder and head and did the engine tuning and rebuild ,
    2012: fork acquisition (from France) and mounting to the frame,
    2013: laser cutting and fabrication of parts,
    2014: sidecover and other parts,
    2015: small stuff
    2015 - 2019: nothing
    2020-2021: final assembly exhaust airbox, ....

    The bike was a TY 125 and in my ownership since 1981!:

    Checking in. Haven't taken it very far into town yet... I feel less like a hoodlum now that it has tags/inspection/insurance.
