The scariest and happiest moment for me was when I was practicing on my own 125 after I passed my CBT and I went into a 60mph area for the first time. Once I got above 50mph I felt like Han Solo doing the Kessel run in less than 12 parsecs.
Having purchased my first ever bike last week, 125cc on my CBT, I sat there in the car park, sat on this bike with the keys in hand thinking "what am I doing". The dealer asked "You OK", I replied "Yeah, thank you".. That was a lie, I was nervous but excited and ******** myself.
I drove away from the dealer... massive smile within seconds then had to go onto a dual carriageway to get home
Coming off the slip road, did my life saver, big lorry, **** myself, he changes lane so all clear, opened her up and from that moment, I knew this was the life for me. Definitely get the Han Solo reference, a truly magical experience that first time.
Tried to do a life saver when going what felt like 88.8mph, as what
@tom_e said, I nearly got whiplash
Nerves, excitement, smiles and a little bit of wee all at the same time.
