    KX250E

    The controller is at 400 Amps x 84V (fully charged)=33,600kw. Plenty fast enough for me

    KX250E

    Update: I made some changes. I scored 2 of those 47AH FOMOCO 12s batteries from BH last Fall. Basically the same size as the SPIMs but 3 times the capacity. I don't have photos, but I cut 2 of the series cells on each pack for 20s. So far they have worked a treat. Relaced the wheels. Replaced...

    Kx100 x QS3000 V3 x Fardriver ND96350 x LiPo28s 20Ahr

    Nice build! Seems like a good drive combo. I want to see how that 4000 v3 fits in a full size bike...

    You could 3d print that chain reduction gasket out of tpu.

    QS 138 70H with Gearbox

    That is a great idea, you should sell those! I feel like the 428 chain size is better suited for the e moto setup, and quieter than a 520

    Looking back on the pictures, there aren't any after I welded the holes closed. When I decided to start cutting I knew I would not be riding motocross or doing any serious jumping with it.

    YZF 2007 Electric conversion

    I went by the guess and check method when I did mine. Ended about .002" to .003" under actual sprocket dimensions. A snug fit, but still will come off without a press. Very nice CAD work!

    KX250E

    It was tough to get everything to fit! Just keep cutting until there is enough room, while still keeping most of the rigidity... BTW 8.46:1 ratio so I get about 53mph before it cuts out(6000rpm)

    KX250E

    Update! Finally got the 260 after waiting for 6+ months. It barely fits under the seat, with some plastics modifications. One thing to note is the Battery positive wire does not go to the B+ terminal on the controller, it goes to the red terminal! Kind of illogical, but it wont work if...

    Then fitting the battery into the frame. Some slight frame modifications were needed to get the battery to fit.

    Some pics of mounting the motor and machining the jackshaft to fit the 6 spline sprockets.

    I decided to document my dirt bike conversion. Lots of research and planning went into it so far. Here are photos of the journey
