I have a 21 AT DCT adventure Red ,White ,and Blue in my garage it has a 21 inch front wheel 19 inch rear ..
THINGS MISSING
-shaft drive
-center stand
-heated grips
-power outlet
-comfortable seat missing…like sitting on a 2x6
-5 gal fuel tank
-an array of windows like cascading menus and settings to memorize
-poor fuel economy over 75 mph combined w small fuel tank the yellow light is on regularly when pounding tarmac to a destination at speed.
Think carefully before you pull the trigger on a new Africa Twin.
Not an apples to apples comparison in my opinion. Sounds like you have buyers remorse with your AT.
-shaft drive - modern chains are much lighter go 30K+ miles and cost a couple hundred bucks and an hour of labor to replace. Ability to change gearing on non DCT model is a plus
-center stand - adds weight but is easy to add for couple hundred bucks if you have to have one.
-heated grips - simple add less than $100 gives the option to use your favorite ones and not be locked in to the OEM ones.
-power outlet - most people do all kinds of wiring adds for electric gear, GPS, a tire pump, and etc. Adding a power outlet that doesn't blow the use with anything other than a phone or GPS plugged in is a big plus.
-comfortable seat missing…like sitting on a 2x6 - I hated the OEM seat on my S10 as bad as the one on my AT and almost every other bike I have had. Many people change seats or there wouldn't the huge after market there is.
-5 gal fuel tank - If your mission in life is to pound blacktop you should have bought an Africa Twin Adventure Sports model with a bigger tank than an S10.
-an array of windows like cascading menus and settings to memorize - Most people seem to want the extra tech that keeps getting more and more complicated on most new bikes. I personally don't like it on any bike.
You forgot to mention the 50+ pound lighter weight difference, extra ground clearance, and better off road manners with the 21" front wheel of the AT when riding dirt roads of true off road.
That's the only thing not easily tweakable on your AT is the 5 gallon tank.
I still own my S10, AT and a T7. I ride them all regularly and they all have different missions for me. That said, if the T7 or other middle weight bikes out there now were available when I bought the AT, I wouldn't have bought the AT. The T7 is a 125 pounds give or take lighter than the S10 and much better on dirt and lots of fun on blacktop. As I am getting old I find smaller lighter bikes much easier to manage on blacktop or dirt. YMMV
