I bought my bike in June 2013 with 1700km on the clock when it was 7 years old. The previous owner used it briefly and then left it to gather cobwebs.
I was skeptical buying a bike that stood for so long, but I am fairly good with servicing and repairing bikes myself, so I took a gamble that seriously paid off. I also bought it for a steal (ZAR14000), whereas new ones are almost ZAR38000 now (May 2014).
I mostly use it for commuting 44km per day, but recently took it on a two week, 3500km solo trip from JHB to Cape Town and back. Long story short, the CBX250 was 100% reliable and consistent throughout the trip. Cruises comfortably at 110 - 115km/h, and got it up to 145km/h for brief periods, but fuel consumption and comfort were compromised at higher speeds. It's comfortable enough for 9 hours riding in a day, and I never experienced any discomfort at all.
I averaged 32km/l on the trip, with about 20kg luggage in saddlebags, which I think is amazing.
I do all servicing myself and takes less than 2 hours and ZAR100 to complete the service. I will use this bike for as long as it lasts, since it saves me an hour a day in traffic, and a small fortune a month in petrol. Super easy and rewarding to ride. It's no surprise I see so many of these in my neighborhood
