First, the manual states 269# with oil and full tank of gas. (doesn’t mention antifreeze but I’m sure it’s included). Tank capacity 2.96 gal Coolant 1.69 quarts. The weight I got. First I tried putting the scale on a bike stand but no matter how I positioned it under the bike I couldn’t read the scale, the dial was covered up by the bike frame and engine. So I went with the measure the front with a block of wood the same height as the scale under the rear wheel, and then measured the rear weight using the same procedure. The scale is a high quality scale that reads to 300#. None the less I can’t verify the accuracy of the scale. The total weight was 251# . That was with oil, coolant (about 8oz too much) and 1/8 th tank of gas. CORRECTED CALCULATIONS Gas weighs from 5.8 to 6.5 # per gallon so the average weight is 6.15 # per gallon. Weight of gas needed to bring it to a full tank is 16. So, 251 + 16 = 267# with oil, coolant, and a full tank of gas.
