    Hey all,

    So I'm buying a 2018 Honda CBR650F and I'm looking at getting a hitch carrier for it for transporting it short distances around town, less than 20 miles at most.

    My question is I know the tongue weight limit on the 2016 4Runners is 500 pounds. The weight of the carrier and the bike is a combined 551 pounds. I have a 2" lift on the rear with heavy duty springs. Is this completely inconceivable thing to do? Whats the weak point to make it only 500 pounds? Is it the hitch, springs, frame, ect.?

    I don't need the carrier, but it would be a convenient thing to have.

    I'd run it. I'd try to keep the weight as minimal as possible, eg almost no gas in the tank, no luggage, etc. I think really the limiting factors are the carrier's weight rating and the distance the bike sits from the hitch - further back means more de facto weight on the hitch.

    Even with HD springs you're going you have rear sag. Airbags are really the best way to deal with that. Even with my 280 lb enduro I'm sagging.

    I have an old thread in the "towing" subforum with pics. Add yours if you get it.

    Thanks for the replies guys.

    The carriers weight limit is 600 pounds so hopefully all works out. Really don't want to drop a $9000 bike on the freeway haha.

    I'll definitely post pictures when I pick it up next month.

    Short trips should be ok, you won't hurt the powertrain. I wouldn't go faster than the speed limit though, braking becomes a factor after that.

    Thanks, I'll definitely be keeping it under 55. I'm sure I'll be too paranoid to do go any faster.

    The weight isn't a factor in "hurting the powertrain", the hitch hauler + bike weighs way less than a trailer, and I think the 4R has a tow rating of... maybe 4,000-5,000 lbs? Something like that. So 600 pounds to "tow" on the hitch is nothing (although Large is correct, there will be some minor braking defecit with more mass). The issue is weight on the hitch and "torque" (for lack of a better word) on the hitch from the hauler moving around over bumps and in corners and such.

    OP, I dragged my enduro cross country and back ( https://meefzah.smugmug.com/March-2018-MMM-Tennessee-trip/ ), over 5,000 miles on a hitch hauler, high speed interstate (105 mph max!). No problems. Again, smaller bike, but same concept. I think you'll be fine.

    I would suggest that you get a set of quality ratcheting tie downs with carabiners on one end and soft loops on the other - for the front of the bike; and either get the same ratchet set or at a minimum get a good set of cam buckle tie downs with carabiners and soft loops - for the back. If you ever have lost a bike because of a shitty 'S' hook coming undone when you hit a bump and the bike's suspension compresses... well, you'll never let that happen twice, I can tell you. My druthers are the KTM Powerparts ratchet straps, they are the bomb diggety. I think they are pictured in my other post in the towing thread that you 'liked'.

    Oh and one more piece of free advice... put your hatch window down when you load the bike. If you drop it towards the truck, you won't break the glass!

    So, realizing that the current receiver is BOLTED to the rear part of the frame I’d heed the weight restrictions. Adding a bike hitch with the weight of the bike on a bit that extends out acts like a lever against the designed receiver. If you’re worried about dropping a $9k bike on the freeway to save money on a carrier I’d seriously reconsider your options and just go with a bike trailer and a lower tongue weight.

    Just my thoughts.

    Most likely you would be fine, but why risk it? I have a little cargo rack for my receiver and even hauling light stuff is awkward. The bike will wobble around and you will probably stress out the whole time. You risk scratching your truck while loading and unloading. When you are done, the carrier will be heavy and awkward and you will need to store it. I would just rent a truck or buy a utility trailer if you have the space. You could use it for Home Depot runs too.

    Well I finally used it. Bike got a flat due to a pothole destroying the rear wheel. Worked fine driving on the freeway at 55 for about 15 miles. It's definitely a short term solution for emergencies. I'm going to look into a full trailer once I have to take it further than out of town.
