Instrument accuracy (or lack of)
Was planning a trip away on the 790 when I thought that with the 14 litre tank maybe I should check how accurate the instrument readings are, so with the aid of a GPS and refuelling at several different fuel stations in case the pumps were inaccurate I came up with some surprising findings.
A + reading means the instruments read higher than the true distance.
Speedometer ......... + 5%
Trip meter ............. + 2.5%
Fuel Range ........... + 5%
Fuel Consumption + 18% ***
Well the speedo error was as expected, +5% error is almost an industry standard these days, my last few cars had a +5% error and also my last 3 or 4 bikes
The trip error of + 2.5% is a little high compared to Jap bikes which are usually very accurate with their trip readings and seem to be around + 1.5% error.
Fuel consumption error of +18% was a real surprise, so my frugal fuel consumption figures of 29 km/l were all crap and a much more realistic figure of around 24 km/l fuel consumption were calculated.
The surprise figure here is the fuel range error of +5%, surprising because I would use use total fuel (14 litres) multiplied by fuel use (which is +18% high) to arrive at the fuel range but the fuel range is only +5% high so obviously KTM have deliberately set the fuel use figure high to make the motor appear very lean and frugal - which it isn't.
BTW my 790 is a July 2018 model with around 9,000 kms running Pirelli Angel GT tyres approx 30% worn and software version 0.17 (soon to be updated)
