Hello guys, I have just sold my R15 V1 as these days I think my back is not getting too much comfortable riding a r15. And also I think I need something powerful but whenever I drive my cousin's ZMR or CBR 250, I feel these bikes are not as smooth as the R15. I've been spoiled by the smoothness of the r15 but I need something which has more outright power than the r15 and the riding posture should also be a bit upright and comfortable. And regarding NS and Duke, the short gearing just doesn't please me as I ride in the highway most of the time and I don't like the engine screaming whenever I touch triple digits. Somehow I feel the Karizma R is more smoother than ZMR, but I've always ridden a relatively older zma and a newer ZMR so the older zma must have been smoother with much usage as Hero engines tend to get smoother with age. Please suggest a bike that has good low end torque, should be smooth to ride without vibs, fuel economy can be compromised but shouldn't be less than 30, and should be a full dc bike for lighting upgrades.
Just for info, the bikes that I've owned till date are - Suzuki AN125, Suzuki GS150R, Suzuki Access, Hero CBZ extreme (dual discs), Yamaha FZS and Yamaha R15.
(I think I should cross the 150cc barrier now..)

Thinking of getting a used zma for some time to test how comfortable it can be for my regular trips..would it be worth???
