With a positive mental attitude Do not be afraid it,s only a 1200
1. Find a bike that fits !
2 Got 1 wrong Try to make it fit (least expensive option )
3 Place seat on lowest position
4 Remove panniers and top box
5 Find some level ground Push bike onto level ground
6 Place on sidestand
7 Make sure level ground surface is firm with no loose grit or banana skins
8 Wear bike boots other clothing optional
9 Stand on left of bike
10 Place left hand on left grip right hand on right grip
11 Grab a big handfull of front brake lever and keep it held
12 Swing right leg over saddle and as you go up onto the bike saddle pull bike upright at the same time.
Stabilise with balls of both feet downwards onto the ground.
13 Unlucky for some If you cannot manage to get here or from here flog the bike and buy a camper
If you can move on to practice with Topbox and Panniers fitted and additional crap added Buckaroo style
Glad to help Frank
