Funny/scary story. About three weeks ago I purchased a Kawasaki ZZR 250' 99 model. Anyway, while riding at slow speed I felt like it was an absolute pig to steer, but once I got to speed up it started to behave better. A couple of days ago I noticed the tyre looked a little flat, so I stopped into Servo to check the tyre pressure and the reading I got was 0 psi. I thought for sure that the meter must have been wrong, because although it looked a little flat it did not look totally flat. By that I mean, if you have a flat tyre on a car it completely bottoms out on the rim and bulges out the side, this looked like it was a little flat but I am also not really sure what it is meant to look like as I am a complete beginner. So, I booked in for a service and the mechanic gave me a ring and asked if I knew that the front tyre was completely flat. I said 'no' and gave the go-ahead to replace the tyre. Anyway, the penny dropped and I realise I have been riding around with a flat front. The fact that it was a pig at slow speed, and wobbly around corners, suddenly made a whole lot of sense! I picked up the bike this afternoon, and wow what a difference! It is easy to drive at slow speed, it feels very light and goes exactly where I point it. I feel like a bit of a tool! I rode that bike at night in the wet with a flat front tyre, amazing I didn't come off.
