I weighed my 750 recently. Front was 100KG, Rear was 120KG. So, 220KG in total.
Over the past week I have stripped the tanks and bodywork off my bike and given it a thorough deep clean. Whilst doing so, I decided to strip all my spares and tools off the bike. I also removed my rear box which carries my stove and kettle along with a tube and other bits and bobs that I can't stuff elsewhere on the bike.
Total weight sans crap = 200KG. On both occasions I had approx 2 gallons of fuel in it.
I am looking forward to a ride and taking in some local trails to see how different it feels. 20KG should make a huge difference to the off road handling and most likely a noticeable difference on road.
So, get the Wife off the bathroom scales and get the Big on them. It would be good to have something to compare mine to.
