Hi there!

I´m offering a used (but in mint condition) conversion kit, which makes it possible to use a KTM rear wheel on a zero fx and zeros using the same swing arm.
Because of the fact, that it is easier to find a used ktm wheel than a zero rear wheel i made this kit.
It has a custom made aluminium 65 tooth sprocket wheel, a spacer 5mm for the axle and 6 spacers with screws to put between the wheel hub and the brake disc.

Iy anybody is interested, please send me a pm or e-mail.

Best regards,

Christian

Hi everybody,

in my opinion the FX has only poor real offroad Qualities compared to my KTM 500 EXC.
If you ride to fast in medium heavy offroad, the motor gets too hot pretty soon, especially with warm outside temperatures.
This comes to a complete stop, if you don´t descend your speed.
But the most worse is the suspension.
The fork is not very sensible and the it has no reseve, if you jump a little bit. (just for your info: My weight is only 70kg)
The rear shock is the same: You can adjust it to be sensible, but then without rest-resource for a hard hit.
Or you adjust it harder, but then without any sensibility.
A progressive rear shock mechanism would have been better here.

To all this comes the very water-sensitive bearings of the wheels and the rear swing. Maybe its only the retaining ring of the bearings, that do a bad job...

Anyway, I have now 3000km on my FX 2013, and I had to change two times the front wheel bearings and one time the rear whell bearings ans well as one time the swing arm.

I have to admit that I do ride in dirty, slashy areas too, because I don´t want to carry my FX over a water-puddle.

So my result is: FX is and motorbike with an enduro look, but better to stay on the asphalt or gravel street. And keep away from water...

I just wonder, because, if you touch the motor outside, ist has only about 40 degrees Celsius. So why should it be inside much more?
Of course, there is an temperature resistance between the copper coils and the outside aluminium housing. But to keep this resistance
 as little as possible should be the goal at building electric motors.

Regards, Chris.

Yes, with my 2013 FX it´s the same. If you ride hard with lot of the time in the upper torque areas, the overheat-symbol is lit.
Fortunately this does not happen when the temperatures drop to 20 degrees Celsius.
The german importer of Zero did some tests with oil-filled motors to get the heat better and faster to the outside of the housing.

Hi Burton!

Do you eventually have the mouser parts list to build an own Y-Adapter?
I can order at mouser and would be happy to get a list with the parts to order.

Hopefully someone of Zero´s staff reads this thread here....

Hi Ray,

when I was dismounting the swingarm, all bearings were pressed in line with the surface of the swingarm.
And so i pressed the new bearings in. I´m just complaining, because I think with other bushings or a "seat" inside the swingarm
it is possible to keep the bearings free of axial force.

I just replaced the front sprocket of my FX 2013. The best way is to remove the swingarm.
For that, remove the rear wheel, the lower screw of the suspension and the screws, which holds the brake-line.
remove both Screws at the swingarm-axle.

Then you have access to the sprocket.

Best regards,

Christian
