"Biker" for me usually means motorbiking, though I also have a couple of mountain-bikes... see Trail Bike
My current motorbikes are a Honda CBR600RR ABS 2017 and a Kawasaki Ninja Z250SL.
Previously I have owned: Kawasaki ZX4-RR (Ninja anniversary edition), Honda CRF300 Rally, Honda CBR600RR 2005, Honda CBR600FW, Honda VF750F, Yamaha FJ600, Suzuki GSX750EX, Yamaha FJ750, Yamaha XJ900, Kawasaki Z750 and I passed my riding test on my Kawasaki KH250.

Falling in love again: big views, big emotions on reclaiming my RR from the workshop following its rebuild. A brilliant ride out but read on to hear about the shooting on the autoroute .
Photographic glimpses GBMCC London’s monthly social meet.
Three CBR600RR in Funchal - my biggest smile of the holiday is in front of a bike just like my own CBR600RR
The big smile and faraway look in my eyes tells it all: Happy Biker! That’s the first time I’ve got on my CBR600RR since being knocked off on the autoroute just outside Marseille in September. Not yet ready to ride but I’m visiting the workshop to discuss the repairs.
I'm riding light for a week on the mountain roads of the Alps. No laptop, although I do have my SLR camera but photos will have to wait till I'm back in Marseille..
I left Marseille for a long ride north via the Col de la Croix Haute (1179 m.) to Saint-Gervais under Mont Blanc. A bit of rain towards the end of the day which cleaned the Provence dust off my white leathers and boots but didn't soak me through.
