I installed these on my bike today with little to no issue. 5 Minute install. I believe these are best for non-ABS versions as the ABS unit is usually in the locations under the seat. But as you can see in the photos there is quite a bit of room under the seat on the non-abs model.

Description from MNNTHBX:

“There’s a lot of storage under the Honda Monkey seat you can’t get to without carrying tools, so we fixed that. Not content with a thumbscrew, we wanted something cleaner. The flush mount Delrin plug and stainless inserts is opened and closed using your ignition key, because we assume you’ll be taking it with you… Sold in pairs.
