## Questions & Answers

**Q: Will this work on a Suzuki dr650se?**
A: 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.

**Q: Will this work on a Grom?**
A: 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.

**Q: Does this work on Harley touring models?**
A: Depends what your exactly trying to jam. Primary? I think so

**Q: will this work on my 2000 RM80? i would be using it to remove my primary drive gear.**
A: Yes, it works great for that and it's a tough little tool.

## Customer Reviews

### ⭐⭐⭐⭐⭐ great tool
*by J***Y on February 8, 2025*

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.

### ⭐⭐⭐⭐⭐ Overpriced, but more than sturdy enough for most jobs
*by D***. on April 30, 2024*

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.

### ⭐⭐⭐⭐⭐ Good price
*by M***E on November 7, 2024*

No worries about jamming wrong thing in and ruining anything anymore. Should have bought one years ago. Great product.
