a dirt bike
No only 2-stoke bikes have powerbands, the xr100 is a four stroke.
My opinion and my knowledge the xr100 is slower than the xr80 because I had both of those bikes and the xr80 always beat the xr100
The Honda xr100 has 5 forward gears 1-down, 4 up.
They're not.
The xr100 uses straight unleaded gasoline. (car gas)
The manufacturer who makes the xr100 is Honda. These parts are for dirt bikes and can be found on many sites such as; motosport, makepolo and motercylezez.

It is unlikely that the suspension from a Yamaha YZ80 will fit directly onto a Honda XR100. The YZ80 is a smaller and lighter off-road bike than the XR100, so the suspension components may not be compatible in terms of size and mounting points. It is best to use suspension components designed specifically for the XR100 to ensure proper fitment and performance.
According to the spark plug manufacturer NGK, the recommended gap for a 2001 Honda XR100 is .028"
100-400
1 quart of 10w-40
