Hi Radar, ID.
Truth to tell, I also did not know that such places existed in india, cause we normally just stay in the cities & towns, and the tour operators only suggest places which are more famous ( and hence more populated). It requires some research and then you just have to go out and figure out if your research helped. 
A couple of trips I have to do sometime. Timelines are not really fixed…
1) A Trip to Leh. This is the mecca of riders. It has the highest motorable road in the world at the Khardungla pass. A few friends from the RD club went on their bikes . The log is at https://www.bikeszone.com/mab00019.htm . This trip can only be done during the summer season, as most of that area is closed due to snow during other parts of the year.
2) A trip around india. Basically India is huge. We have read about it in History books and geographic books (in school), but have not really seen most of it. So I am planning on this ride too… Most probably this will need to be done during spring or autumn so that both the south and north can be covered. The issue – I need a month off from work !!!
I will keep you updated if these plans materialize.
As rajnish mentioned, most people prefer the bullets for rides. This is due to the fact that they are the only tourers available. However, we do have people doing the trips on other bikes. I use my CBZ, the link given above has RDs touring, and another of my friends did Leh on his pulsar .
India is a beautiful country – if we get away from the towns and cities.
