I purchased the Max carrier for a 6000 mile trip to haul my KTM 500 EXC across the US for a trip from MI to UT and CA and back to MI. The carrier was simple to load and very stable, including on some very rough roads. My only point on potential product improvement is the mounting bolt and washer for the hitch receiver. I am using a GMC 3500 HD pickup for the haul vehicle, and the 2.5" receiver requires a larger washer (essentially a heavy gauge fender washer) on the bolt head side of the bolt to properly tighten the carrier to the receiver. I had a fender washer in my stock of nuts and bolts, so arguably a very minor consideration. Including a larger washer in the kit to accommodate 2.5"receivers could be a nice change.
The Max version of the carrier is likely overkill for my KTM enduro, although I wanted future proofing for my street bikes. Overall a great product and kudos to my brother for encouraging me to go the Mototote route vs. the cheaper (build quality and performance) options at the tool stores.
