Q. I am 5.5 height is it Ok or not for me to ride the Himalayan bike?

Yes, it is.though it would have been better if you were taller. you can visualise the benefits of height in slow moving, bumper to bumper city traffic or x country (off roading) where a taller guy is expected to have better control of his bike. you may even have problems in stability with a pillion pillion on slow speeds. while fixing up the accessories, you may not like to fit additional seat cover which are either pneumatic (air filled) or gel based since they would add around an inch and a half or two to the riding height; as well as the handlebar risers may make the ride uncomfortable for you. the panniers would similarly obstruct your exit and entry to the bike while the top box would almost make that impossible. this is not to discourage you, but this is exactly why you won't find many lady drivers (unless she is large or extra large frame). as an alternative, you may even try and consider hero xpulse 200.let's cut out the theory part. go for a test ride with a friend who owns a re himalyan; or if none of your friends own one, or do own one but are too posessive, head to the nearest re showroom where the over courteous staff would help and guide you.happy riding and all the best.

It should be bit of disguesting while parking on slopy surfaces, am 5'8 and have faced difficulties 3 times while parkign on declined right side and it fell down damiaging the side indicators. so would not recomment less tha 5'8.

It's a tall motercycle I would suggest you to take a test drive it might be ok after a while but will definitely have some issues tho.
