I hit 89mph today with mine and didn't notice any instability compared to before I installed the cases.

Your right side case is bigger than my first apartment.

I’ve maxed my bike out at an indicated 131 MPH with 10inch Jesse’s including the top case.  I also run 705 Shinkos front and rear at 35 PSI. It was rock solid. Awesome bike

tire pressure the first and most important item to affect your motorcycles handling . weight distribution or balance can effect handling in a dramatic way ( what you have in those panniers ) . suspension preload is  another factor that alters the handling dynamics . weather conditions ,say lots of wind to push you around . and if I may add , what's the point of extreme high speed all loaded down with boxes , they sell hayabusas for that ( just curious ) . the type of tire you run also can change handling (feel for sure ) dynamics . my suggestion is slow down and enjoy the ride. or not..... I have toura tech hanging off my bike , no issues except for previous factors listed......

I've never experienced any handling issues with my Jesse bags installed, the Tenere is rock solid.  I would check tire pressure, and wear.

RCinNC, you are correct about the 46 liter case being huge. You're comment had me laughing. I'm still debating about getting a 33 liter case for the right side; wish Givi made a Trekker case between the 33 and the 46.

They must make it a real adventure when you have to thread your way between objects.  Lane splitting would be a real heart-stopper.

DO NOT  inflate them to the owners manual recommended pressures. Not that they will explode or anything like that, but there is no advantage in doing so. Over inflating "could" be a cause for instability at higher speeds because they are designed to run with a maximum of 33 psi, both front and rear.

While it's true that the 804/805's have a maximum pressure rating of 33 PSI,  the 705s however have a maximum pressure rating of 42 PSI, same as the OEM tires.

No, guess not it says 805 doesn't it.  I'm reading challenged today!

Also, keep an eye on the tire's speed rating(s).

Yep my standard pizza boxes (there's a note in them ... Do not exceed 85 mph with these bags on ... and other stuff) like made you feel there's not enough weight on the front end (at 80+). But rear tire pressure increase (technician at Yamaha told me use 39/40 instead of 36 psi in the back with bags on) ... and it worked some (running at 33 psi on the back did definitely not work on one blustery day), rear tire make (the old BWings on the new bike needed 40 psi with bags (maybe due to soft side walls), Pilot Road 3 and 4 were a lot better, now Battle axe Adventure X40R seems every bit as good as the P. Road 4, Michelin Anakee 3 had low traction ... open up out of bends and you start drifting at uncomfortable speeds, but offers another way of taking corners), the high screen supplied as an accessory (replaced it with the standard screen .. big difference), as mentioned blustery conditions (with bags the bike don't like them), the rider (I rode sports bikes and a Vmax before the S10 and they are much firmer up front)... I was holding the bars too tightly and a few sessions with finger-like contact in blustery conditions and making an effort not to correct made things a lot better. If I had to put them in order I'd say ... rider> the high screen>rear tire pressure>tire type... all can make life interesting in blustery/high speed conditions. Now I only exceed 85 with the pizza boxes, little wind and spider senses on 'max'. I am now running (with bags) at 33 front 38 psi rear, standard screen, Battle Axe Adventure rear (still Pilot Road 4 front), and that's OK. Without boxes different bike ... 120 no problem.

The Tenere manual specifies 33-F/36-R for loads below 198lbs.  It changes to 42-R when load exceeds 198lbs. (front tire pressure remains the same)  Of course, those pressures are for OE BW tires.  I will have to experiment when the A41s get mounted; starting with the OE pressures.  I generally don't go much faster than 80mph with the bags mounted; I can tell how much they hang out in the wind by the amount of bugs on the fronts of them.  ::001::

I'm fine to about 110-115 indicated mph, then front wheel wants to wobble a bit. Was thinking about taking OEM bags off and seeing if wobble was still there, but haven't done it yet.
