Hii Guys i am sampath I booked my YAMAHA SZ-X when it z released and I got it after n month now am using it n I have driven 1000km n gone for 1st service coming to the bike am really really very satisfied its an amazing bike no wonder if u want to go for an 150cc bike go for sz-x an d surprising thing z it comes down around 60k oh my god can u believe it 150cc bike around 60k. Am very comfortable with d drive with stylish look n d engine sounds good no vibrations an no sound it z very smooth and pick z excellent and power comfort awesome.. and suspensions are good and drum with 150mm z also not bad last but not d least mileage its all depends on d drive for me it z gvng around 48 in city and 56-60 in highway before first service lets c how it gives after first service no I guess no matter it gives around 50+ in d city n 60 in d highway. coming to the negatives most of d material z plastic instead of metal which looks very dusty and missing things r Disc n Digital meter if all around it comes for 70k wid disc n digital meter diz would b d best bike in all 150cc. All around i am really satisfied it z money worth bike all d middle class ppl who would like to go for 150cc bike diz would b best bike.
