A few people have been scammed on the site, Only use paypal to pay for items for sale by other members. If they will not use paypal, its likely a scam NEVER SEND E-TRANSFERS OF ANY KIND.
I prefer no pillions , camping gear takes their place , I like solo rides I don't race or rally , I've ridden in clubs, groups etc . My brother 10 years younger is quite a good riding touring companion.
I would recommend a puncture sealant in the tyres , I always fill each new tyre, a cheap offcut of sheepskin to sit on , take chainlube ,talc powder, & a supply of earplugs.
