I got HH Karizma R recently . Here I am going to give a honest review.
*Positives:*
Looks, Riding comfort, Smoothness, Pick-up are Excellent
Electricals: Except head light rest are good.
Gear shift is very smooth.
The suspensions are at their best(Its HeroHonda Special).
New Karizma R, graphics are excellent. Rear suspensions with red colour are very good.( purely personal choice, some people may not like them)
Engine cover is sporty.
Best suited for long rides, u wont feel any kind of stress.
Excellent service from hero Honda.
All spares will be available, some spares are on costlier side.
There will be no questions regarding engine life, efficiency, spares quality. All will be up to the mark.
HeroHonda brand is one of the biggest positives of this bike.
*Negatives:*
Tyres: should have been bit wider.( u can change them later, so shouldnt be a big problem)
Seems to have a little problem with self starter in winter.
No crash bars, because of which minor accidents may cause costly repairs. No matter how good you ride, accident may happen. So should be very careful.
*Fuel efficiency** greatly depends on riding conditions, and how good you ride. A decent ride can expect around 30Kmpl in city road conditions and 45Kmpl on highways. So this cannot be put either in +ves or -ves, **it depends on u.*
Another important point related to HH Karizma R is that u can have extra accessories without losing your warranty. My bike has anti-theft alarm, which is certified by HH.
