I am going to review Yamaha YZF-R1 so lets get started
Mileage
Mileage of the bike is totally bad this bikes gives a mileage of 15 kmpl on highway and while riding on city suddenly mileage goes down to 3 to 4 km.
Comfort
Comfort of the bike is fully worst because of the bad design it creates back pain for both rider and the pillion because of the bad sitting position.
Reliability
I am not reliable with this bike because it always disappoint me
Road grip
Road grip is average
Appeal
I appeal to all that dont go through this bike choose another one.
