Reminds me of the days when the day of the week it was made determined the reliability of the vehicle..
Can't really comment on this bike due to low mileage, but my previous bikes (Honda, Suzuki, Kawasaki and Yamaha) always just worked and i never had any reliability problems with any of them on the daily commute in all weathers.
The only issue was the rider who in his younger days preferred life on his arse sliding down the road.
I can comment on BMW cars, i have a 2007 5 series which on the forum i belong to are either working perfectly or are money pits, luckily mine is the former.
