I have the luck to own a S10 2012 and Explorer XC 14... I have been reading your comments and impressions about these bikes...I want to put my two cents and provide a bit of insight about these fantastic bikes...
Look:
While riding both bikes I had received more compliments with the explorer and in my opinion the Tex looks awesome in flat khaki green.
Ergonomics:
The S10 feels more natural and relax, while the Explorer is a bit more sport touring position, don't get me wrong both bikes are very comfortable... The S10 has more leg room when compare with the seat in both bikes in the higher position.. In both bikes you can reach the floor easily...in the S10 you have the feeling that your are loose in the saddle and no secure...in the other hand, in the Explorer you feels like locked in position and you feels more secure...during sport riding the Tex wins in ergonomics...is like attack position..
Brakes:
The S10 has better brakes overall, the linked brakes gives you more stopping power...in the Explorer the brakes are not linked...both has ABS although the S10 system is better...what I like about the Explorer is the feeling and progression of the front brake, the S10 feels a bit spongy and poorly progressive...at high speed the combined brakes are exceptional..
Suspension:
The S10 has better front forks, they are fully adjustable, better damping and more progressive....the Explorer has preload adjusment only and the forks botton out easily during hard braking on bumpy roads....the rear suspension is the opposite, the rear in the Tex feels with better damping and better control, also the Tex has external nitrogen reservoir and resist abuse better than the S10...feels even better than in my GS...
Engine:
The S10 feels sluggish and agricultural when compare with the triple...The tenere has two engine modes which are very different, one is very progressive and nice for off-road, rain or around town in trafic and the other sport mode feels like more powerfull and quick especially in the three first gears..the Tex does not have modes but feels like it managed to do it all pretty good with one mode...The Tex is fun, very powerfull and addictive....never feels sluggish and underpowered, especially in hilly terrain or while driving with passenger and fully loaded...fueling is very good in both bikes and both bikes are throttle by wire, although with different systems...The S10 seems to be a more robust system, and the feeling is more standard..the cruise control in the Tex is very nice to have and put less pressure in your wrist with a softer spring....
Handling:
The S10 is more stable than the Tex at high speed and when fully loaded, in the other hand, the Explorer feels more nimble and quick in the twisty roads, the S10 feel solid and more balance at low speed, but once the explorer gain a bit of speed the high speed instability pays off, giving you a more sporty and nimble handling when is more important, when having fun with curves....in my opinion the Tex wins here...the feeling is like you have power steering in the Tex and no assistance in the S 10....my experience was based in several trips with same tires and same roads...
Quality and finish:
Both bikes are outstanding in this department, although the Triumph seems to have more attention to detail and nicer equipment, like the aluminum handlebar and better finished raisers and gear lever, as well as handlebar controls...I think the Tiger has the edge in this department..
Wind protection:
Both of my bikes are equipped with OEM accessories and OEM tall windshields, the S10 offers better rider protection and better heat management than the Tiger.. The Explorer put more heat on your legs during hot weather....although the S10 does a bit on your left leg during hot weather riding...
Reliability:
Both bikes had been very reliable so far, only the Tenere has experienced mild oil consumption and none on the tiger...my ECU was replaced on the Tiger despite never experience a problem...
Conclusion:
Both bikes are very nice adventure touring bikes, with pros and cons, one with more dirt capabilities and other with more road capabilities. It is a matter of preference and I am lucky to share my life with these two magnificent machines...my two cents....
