...and it's a cracker!
I looked at all the 125s on the market, and was put off by the Aprila and Yama's price tag. A review last summer had the Derbi as a dark horse beaten only by the Aprila, and I picked mine up nearly new, pristine for £2k.
I have been riding bikes for 3 days now, and I love this bike. 0-30mph is rapid, and the 4th gear is a laugh out loud grin fest.
I pulled up at work (motorcycle insurance!) and had a flock of people surround me, all very positive in praise of the looks and sounds (the bike, not me).
I plan to ride this for a year, so I am super confident by the time I move up to my next bike, a GSXR 600. This will definately do for now.
