    the difference between the sl650 and sl750

    Is the only difference the cylinder/piston size? or does it run a different crank/rod?
    I have noticed that the cases seem to be sold as either or. Thanks

    Cases and crank are the same.

    750 has bigger cyls, pistons and heads.

    Also use a different flywheel, magneto/elec stator, CDI and impeller.

    ok, I was wondering where they were making up the other 100cc I guess its easily done with 3 cylinders.

    650 = 65mm bore X 65mm stroke (68 HP)

    750 = 69.72mm bore X 65mm stroke (80 HP)

    780 = 71.3mm bore X 65mm stroke (92 HP)
