SilverBurgie,

The mounting rack is very small, and flush with the back of the seat. It is not really large enough to be useful as a carrying rack for other items. Removing and installing the E52 on the rack is about a 5 second job - no big deal.

My own recent tests indicated that the E52 top box did not cause any significant mileage penalty (about 1/2 mile per gallon at most). It does however, knock about 7 mph off of top speed (I did 115 mph without, and 108 mph with).

I ran the tests because my mileage had dropped, and I didn't know if it was more due to the large windscreen I had added, or the Givi E52. It turned out to be almost 100% due to the windscreen.

Stormsteed,

Clearview XXL screen and Givi trunk was getting me 43-44 mpg.
Removed both.

Stock screen and no trunk = 51.9 mpg.
Stock screen and Givi trunk = 51.4 mpg. *

* I did three attempts at top speed on this tank (none on the prior tank that returned 51.9 mpg without the Givi trunk). So, the wide open throttle runs were probably the cause of the mileage drop, more so than the addition of the trunk.

I tried reaching back while riding to see where the wind was contacting the trunk (with the stock screen at about 70 mph). It seemed to be just brushing the sides. I think that at speeds over 100 mph the wind does collapse around more and hit a greater portion of the trunk, creating some drag - but I wasn't about to take a hand off of the handlebars to check...

Admittedly, there are some variables with this sort of testing. The gas pump may not shut off at exactly the same spot when filling the tank. Wind conditions can change between rides. There is other stuff too. But I did ride 150 - 160 miles each configuration. I did ride pretty much the same route. Wind conditions felt similar. And I even filled up at the same gas station and pump. So I think these numbers are fairly accurate.

SilverBurgie,

It would be interesting if you would run a mileage test before you install the XXL screen, and then again after. It would be interesting to see if you get similar results. Riding behind the Clearview XXL is very comfortable, but the trade off in lost performance and fuel economy was huge. I may have to go back to using it at some time, but for now I am trying to learn to live with the stock unit. The old design Clearview XL that I had was not as bad - I got 47 -48 mpg with it - and it was still pretty comfortable. I wish now that I hadn't sold it.

A quiet helmet is definitely key to riding with the stock screen. My older Shoei RF-800 is the quietest of the three helmets I own for that. The RF-1000 is a completely different design. Sad to say, it doesn't fit my head right. And Rider Magazine agrees with you that the RF-1000 is not as quiet as the previous models. I always liked Shoei's, but they have eliminated me as a customer now due to the new design.

Bugs. You'll still get them of course. You'll just be wiping them off of the Clearview instead of your faceshield. :cry: In truth, it is easier to wipe a faceshield that that big windscreen, but bugs won't hit your hands anymore, and you won't go cross-eyed when a big bugs splats right between your eyes on the helmet faceshield...

I don't carry anything in the trunk usually except for my regular glasses, sunglasses case, a hat that I wear when I get off the scooter and maybe my bug cleaning stuff - no real weight or bulk to any of that. I use it when I stop to stow my helmet, jacket, gloves, etc. - same plan that you have. The stuff that I want to have with me, but access less frequently, goes under the seat. I did miss the trunk when I was riding without it.

Enjoy your new accessories when you get them, and be sure to give us feedback on your satisfaction with them.
