I bought my first bike in 2007, but I have owned six ones already.
2001 Kawasaki ZR-7 (the first one, wrecked after 9000 kilometers.)
2005 Yamaha FZ6-N (I rode this bike about 13 000 km)
2007 KTM Super Duke (about 30 000 km)
2008 Ducati Monster S4R Testastretta (about 4000 km)
2009 KTM RC8 (about 10 500 km)
2007 Buell XB12STT (the current one, I have ridden this one about 3700 kms so far)
