The 790 now feels like it actually HAS a steering damper. In my opinion, the 890 is what they made after the initial issues were discovered in the 790. Both Duke and Adv. The 890, while a little more expensive, is going to be a longer-lived bike on average I bet just because they made the mistakes on the 790s first, went back to the drawing board a bit, and came up with the 890s. clamjumpr • 2 yr. ago.

And worse than that, KTM is refusing to accept liability leaving owners in some cases with a major bill for engine rebuild. The clutch on the 790 is wet, meaning it relies on an oil feed and it seems the ASKKTM. I have been heavily interested in the KTM Duke 390 for awhile because it seems like a good beginner bike, only thing stopping me from purchasing one is I keep hearing about reliability issues. Although I also hear some peoples run forever. The short answer is: Yes, the BoosterPlug and the O2 (Lambda) sensor will prevent the motorcycle engine from running too lean - with or without the catalytic converter in the exhaust system. As mentioned above, the O2 sensor will adjust the air/fuel ratio in closed loop mode (High RPM), so the decat will not damage your engine. But at idle, low This is their 790 Adventure Windscreen. Available in Clear, Smoke and Dark Smoke to suit your needs, these screens not only deflect turbulence they do it in style. Features: 4.3 Inches Taller than OEM 790/890 Adventure "S" windscreen. 8.8 Inches Taller than OEM 790/890 Adventure "R" windscreen. Direct OEM fitment. May 24, 2010. Oddometer: 55.

I could start the bike by shorting from battery positive to starter relay output. It started that way quickly. FIND ISSUES; COVER GALLERY The engine is the same platform behind the enviable stats and output of the KTM 890 ADVENTURE R: with a 20% increase in rotating mass over the KTM 790 platform Having experienced most of the common failures on the 790 (mine is a 2019 with only around 17k KM on it. 3rd clutch, 2nd set of cams, 2nd O2 sensor, 2nd rear brake ABS sensor, rebuilt shock, etc.. etc..), I had been pretty lucky with electronics.. up until a trip a week and a half ago.

Listen up fellow inmates with the KTM 890 (& 790 too) cold start issue: according to the NHTSA rep I have been dealing with, Santiago Moladano, the NHTSA is data driven and if they only have a couple of complaints about an issue, that issue is going to die. cU2epLJ.
