Will this work on a Suzuki dr650se?

Should work. Though it’s made of soft aluminum and doesn’t hold up very well. I would recommend an EBC brand clutch basket holder or the Suzuki tool for holding the gear on the end of your crankshaft.

Will this work on a Grom?

It will work on anything with gears that you need to lock up but not damage. Holds the gears so you can loosen a nut or bolt.

Does this work on Harley touring models?

Depends what your exactly trying to jam. Primary? I think so

will this work on my 2000 RM80? i would be using it to remove my primary drive gear.

Yes, it works great for that and it's a tough little tool.

Love motion pro tools, they're always very good tools. This is no exception. This gear stopper fits in and stops gears from turning like it's supposed to . Love it. Great tool.

Es mucho más pequeño de lo que parece en la imagen, tiene el tamaño de casi un pulgar. Aún no lo he usado Pero realmente no creo que dure. En el cartón hay una advertencia de que no se puede usar con pistola de impacto.

I got this when I was rebuilding my dirt bike engine. I don’t know how I would have been able to properly torque the nuts and bolts on the gears without this and without damaging something. The magnet on it is great for holding it in place as you rotate the gears.

Works well, and the magnet is great for hands free use. But like all motion pro stuff you are paying for their name more than the product itself. However, this is much cheaper than the Honda factory tool.

One of the best tools I own for doing motorcycle engine rebuilds. It makes getting tight nuts/bolts out without damaging gears super easy. Hands down can’t live without.
