Nope...glove box inserts are separate option/added price (of course). Stock lowers come w/snap-on cover & inside is plastic...glove/liners give the cushy innerds, but I kept mine stock.

screw the heat on your legs what about the extra motor heat. I have tts mastertune and did data gathering with lowers on and off and with off on same course conditions the engine temp was always lower with the lowers off. this was in fairly cool weather (under 60*) so not sure what difference it would make in 90* temps.
Now my buddy had the soft lowers and his actually ran hotter with them on then it did with them off.

I leave mine on year round. Helps with the rainy season here in SW FL, helps with some wind buffeting especially if wearing a helmet. Without them, the wind gets underneath the sun visor on my helmet and lifts it. So I like them on year round

I always keep mine on even 100 degrees weather here just open the adjustable vents, feels little hot when in stop n go traffic but here in Ca you can split lanes and keep moving.

or you can avoid doing any cutting and just remove the doors during the summer months and then reinstall them in the fall.
from what i've heard, the engine temps are actually lower. the way the lowers are designed, they funnel air right to the cylinders. now i can't say that i've got the equipment to actually measure this to verify if its true or not....

I had read the same thing in American Iron but if you have a TTS Masterune it has a data collection function and engine temp (heads not oil) is logged. I can say that on my particular bike (2011 RGU) engine temps per data logging are lower without the lowers. fresh Air intake temps were also higher with lowers in place. It would be interesting to see if others with data logging capabilities had the same results. I would perfer to leave mine on but after seeing the data I have mine off.

With lowers I run oil temps of around 200-205° when moving >45mph in summer (S. LA), and 230° is the limit so far in gridlock traffic, but when moving even in slow city traffic it's rare to see temps climb >210°F in summer. Keep in mind that I have an oil cooler, which is very important in controlling oil temps, IMO. I can monitor head temperatures, etc., in real time on my Power Vision display unit, and they stay at around 225-235° in 90°+ weather while moving along on the backroads, going up as speed decreases but rarely >280° in traffic. I didn't have a way to check head temps before adding the lowers, so I don't know the difference with vs. without. I run stoich (14.6:1), which makes head temps run a bit higher than richer AFRs. I think my engine temps are in control and well within an acceptable range, so I won't be removing the lowers to do any testing with and without.

HD warns you not to use soft lowers when air temps are >50°F.

they do come complete. but like iceman said, the inserts are extra. but you don't have to have the insert. if you just want the basic box, with the snap on lid. it is included.
