Sadly I just sold my 690 Enduro earlier this year; just wasn't riding much anymore. When i did, we used to put in big mileage down in the pines. 125 mile days were the norm when doing a lap through Byrne, Wharton, Pasadena, Chatsworth, etc. Some advise from a 690 owner to another, drop your gearing as even though the 690 has a close ratio tranny, first is a bit high and you'll be feathering a lot in first on singletrack. Contrast that to guys riding smaller, true enduros who'll be in 2nd or third gear on the same trail, you'll want some more low end. Dropping 1 tooth up front and several in the back for a 10-12% overall reduction is a huge advantage.
Also, not sure which tires came on your R, but if its an on/off tire, get some DOT knobbies like Pirelli Scorpion Pro's, XCMH or equivalent. On/off tires like MT21's or Karoo's are a traction nightmare, especially when the ground gets soft and churned up in the summer. Get some armor/protection on the bike. The 690 radiator is large and the sides are vulnerable and the KTM factory rad guard kit is worth it. Same goes for the underside, get a skid plate. Also, the factory muffler is super heavy and gets insanely hot.
At some point, throw on a better can (Leo Vince, Akrapovic), a foam uni filter and a reflash and the low end response will be vastly improved. The bike has a habit of sputtering or stalling when tractoring through slow areas in 1st.
The only trouble area was the fuel pump which was faulty from the factory in the earlier models. IF it hasn't been replaced with the revised part, do that asap. Sadly this was not a recall item.
The display can also experience an issue where "dust" forms from vibration causing plastic to abrade and cloud the gauges. This was a recall though i dont know which years were affected.
Otherwise the bike is pretty bulletproof. A tank bag is a good idea to carry the oem toolkit, a tube patch and C02 inflation kit, tire irons and a tow strap (for towing the Husky riders when they break down
).
