Front tire = 18-22 psi.
Rear tire = 24-28 psi
My G5 was very stable with higher tire pressures like 26 psi front/ 30 rear but it rode a little hard and the tires seemed to be a little skittish.
At the lower pressures it rides smoother and the steering response is excellent.
The only negative I can think of concerning the 2010 models is the lack of a kick starter.
I seldom use mine on my 2011 but if I were buying one I would try to use the kickstarters absence as a good reason to lower the price.
Since vishuonline says it's NEW, he should know that the new Royal Enfields come with a spare inner tube, throttle cables and clutch cable plus a can of black spray paint.
Also, being a new motorcycle it should come with the 2 year unconditional warranty.
(The dealers memory might need to be jogged to remember these things).
Its also a good idea to ask for a new oil filter because as we all know, their special and will need to be changed at 300 miles.
I guess I was lucky because my dealer also made a copy of the UCE Service Manual and the Parts List Manual on a couple of DVD's. He had these as a PDF files so it was just a matter of a minute for him to make them.
(I know there are a lot of dealers who won't do this so it forces the owners who want them to buy them from our host but it's worth asking about anyway.)
