I bought my SZ-R three months ago, before buying that I read all the review here which was kind-off mixed rating. So after the use of three month with my SZ-R here is my take. In one word I can say its "Awesome".
First when I went to the showroom I was fell in love with the style of SZ-R, After looking the colors I took white one, because bike comes with dual color with the combo of silver grey.
So black, blue, red looks so odd to me. Salesman hinted me that the mileage will be around 45-50 KMS, but I took that as 40 KMS because I know only in dream I can get 50 kms in Yamaha bike.
But bike is awesome cool, Butter smooth driving, excellent pick up, less noise, its just wonderful.
Cons
After 3 months I am getting mileage of 40 KMS, its ok. But for me tyres are so bad, they put TVS tyres and it really sucks.
Other than that SZ-R is super cool!
