No RC book, have only road tax challan.... is it enough during police verification

Hi,

As mentioned in my previous thread, http://www.xbhp.com/talkies/touring-...bangalore.html

I am riding to Shavana Durga hills (instead of pearl valley) on this Sunday (If any one is interested can join me). However, as my bike is a new bike I haven't yet received the smarcard of the RC book and showroom guys have told me that if police asks I can show them the road tax paid challan.

Is this enough if we are going for long rides or will police create a problem if we show them road tax challan with out a RC book/card
