1200 Sportster: Fuel consumption
My wife has a 2020 (MY18) 1200 Sportster with low milage. It has no issues however my only concern is the fuel consumption. It averages about 25km/l during normal riding (100 km/h or 60 mph) - that I think is nearly 60 mpg (US). Is that not too lean? It rides smooth and no other indication of leanness apart form the consumption figures... I bought a new FP3 Fuel tuner which I am tempted to install. Your thoughts regarding the consumption please... Regards!

60 mpg seems a bit high, I think most 1200s get 45-50 mpg from what I've read. My Hammer 1250 carburetor bike gets 45 mpg regularly, and I've got it tuned on the richer side with a 45/190 jet combo, CVP Velocity Needle which I think also richens things up. Plugs a nice brown/light gray. Of course, you have EFI so maybe they run leaner, but you can also adjust them.

That does seem high but if you're just cruising along I could see it. If the bikes not surging at lower speeds, popping a ton on decel, or pinging under heavy throttle, I wouldn't worry about it.

I don't get 25km/L (4L/100km) out of my 1200 at those speeds (exhaust, intake, tune) but it's still got 883 gearing so it revs higher at the same speed. If I were to lower the speed to around 80km/hr (50mph) and ride focussing on trying to get great fuel economically perhaps I could. I don't think it's anything to worry about.
Maybe your wife is just a really economical rider? 🙂

Yep. $5.05 a gallon where I'm at right now.
