you had the test of 180cc before so downgrading to p150 or any other 150cc(except r15) fi or carb bike will make you feel bored.
rtr 180 abs
is a good bike. only bike in 1 lakh segment with abs
. performance and top speed wise it's a bit better than p180.
bikes to look for are rtr 180 abs
, karizma r, p220, 200ns, zmr( bike with best mileage of 51.5 in highways tested by overdrivei in 200cc class). if you can afford a bit more, go for r15.
all the above bikes are tried and tested, pick the bike that suits you after test riding
