The tank is stock; I was no more bothered by the autonomy than by the absence of a fuel gauge on the 2018 model. I usually try to fuel up every 150k and before hitting the trails. What I love about the 690: The torque. So much torque, so fun. Highway ride and passing are really comfortable. This Magnum Tuning KTM 690 Enduro R Performance CDI Box increases the rev limit by 20% over the factory rev limit. In addition, REV PRO KTM 690 Enduro R rev limiter implements a re-mapped timing curve which yields a extreme Max out in Engine Potential and low- and mid-range torque. (Fuel controller recommended). 690 SMC + 690 ENDURO + 690 ENDURO R from 2008 to 2010 included. 690 SM, SM limited, SM Prestige, SMR (all beaksters). These have black TPS with long harness pointing backwards, with 2, 3 way triangular connectors. TPS THAD: 0.5 V / 0.54 V with throttle blade closed (pushed closed with your finger) AND the same at rest, 0.70 V / 0.74 V. TPS APAD Mine gets insanely good fuel mileage with all kinds of mods, like 50+ mpg in Enduro setup. If you put SM kit on it and ride it 100mph all day, it drops to the lower 40s, like 42-45mpg. Link to comment It’s a pukka round-the-globe adventure bike, especially as an Enduro LR (long range) version, which was introduced for 2020 with a 25-litre fuel capacity – with 60mpg easily achievable, that I had three separate instances of stalling with my 690. The first was a nearly broken wire on my aftermarket kickstand cutout switch causing random stalling while riding. The second was a cracked ceramic insulator on my sparkplug causing it to ground out instead of the spark reaching the cylinder. The KTM 690 Enduro R also weighs only 139 Kg, an important characteristic considering that it’s being marketed as an agile bike ready to tackle a wide range of terrains. To the OP, I'm surprised you never said anything about the seat; instead you chose to comment on the tank and no saddle bags. I could think of million of other bikes that would tour 100x better than the 690/701.. all of which have MUCH more comfortable saddles, a proper windshield, more fuel capacity, probably a fuel gauge, better instrumentation, probably better engine harmonics, etc This fuel tank can be used only with KTM 690 Enduro model years 2019-23. In case you’d need fuel tank for previous models of KTM 690 (i.e.2008-18), then please order HERE .
