For years I have been riding back and forth to work with my backpack strapped to the seat behind me with Rok Straps. It has worked without issue, but still a hassle everyday to strap down the bag and hope that it does not coming flying off at some point during the ride, so I decided to add a Givi V46 top case to the bike to carry some essentials, such as rain gear, and also have a place to store my bag while commuting or a place to store helmets and jackets while at a stop. This is what it looked like with my back pack strapped to the rear of the seat.
To mount the top case to the bike I replaced the existing passenger grab rails with a rack from SW-Motech. I preferred this rack over the Givi option since it maintained a similar setup for the passenger grab rails. The next photo shows the grab rails that were removed and the new parts from SW-Motech.
The new rails mount using the existing grab rail bolts and rubber bumpers.
Since this rack is not specific to the Givi cases, an adapter plate needs to be installed for the particular brand of case that you are using. It mounts simply enough with three cam locks.
The adapter plate came with two sizes of rubber bumpers to fit between the mounting plate and the case. The directions suggest fitting the thinner bumpers first and then if the case is rattling to replace with the thicker bumpers. The thinner bumpers worked fine for me.
The Monokey case is very easy to mount to the plate and locks in securely.
An accessory back rest is also available. I installed this too which requires drilling two mounting hols in the new case, but very straightforward with the provided template.
I debated back an forth on the size of the case, but I don’t think that I could have gone any smaller than this one. The Monokey cases have a carrying capacity of 22 lbs. My back pack fits in the case perfectly and with the current load of laptop, tablet, phone, 11″x17″ plan set, and other miscellaneous items weighed in at 15 lbs.
In the end, it looks good to me on the bike, will hold my essentials, and didn’t fall off in the first test ride, so I think this is going to work out much better than the Rok Straps for consistent carrying of items on the bike.
