Thanks to my personal situation, I have to ride my bike from Northumberland to South Oxfordshire on L plates. This means no motorways, taking my journey to 300 miles on a Honda Varadero 125. Now she’s a beauty, my bike, but naturally I have a couple of reservations. I thought I’d ask some of the, ahem, more experienced minds on here about how to prepare, how not to kill myself, the bike, or anyone nearby. Tips?

Well folks, it's that time in somebody's life where we ask that age-old question; what 125cc bikes are suitable for taller riders? I've seen the question asked many times but nothing awfully recent, so I've thrown myself in to refresh the pool. I'm about to turn 17, I have my CBT, and I'm 6'3" (with a bit of growth left in the tank). Assume that my budget is about £60 and a packet of Quavers. Any advice on which direction to go for my first bike?
