I Bought Suzuki Slingshot in April 2011, till now done second service and 2800 kms, Sorry to inform you the bike has a poor mileage around 45 to 50 kms . The Co claims 60 to 65 kmpl .
Why should anybody buy a 125cc bike which gives only so less mileage. So guys better go for a 159 cc bike which easily gives 50 to 55 kmpl but will give you more power and more mileage. For me I have made a wrong decission of buying Slingshot will exchange it with any 150 cc good bike.
