rear brakes are worst

1.service is worst.
No proper technical staff.
2.Regarding Bike suggestions:
a)The welding at the chain and the other side looks very odd,so please go for grinding & painting.
b)The rear brakes are worst-Due to the linkages there is kud noice,braking efficiency is very less.No smooth braking.
c)Gear shifting is bit tight So it can be further smoothened.
d)Mileage-35km/Litre if we ride at 100km/hr.and 4okm/Litre at city conditions.
e)Engine vibration is more.So they are transfered to rear foot rest which can be clearly felt.
So proper dampening from engine to body is necessary.
Please try to improve on this.Believe me No one can beat this bike.
Once again please Improve service.Concentrate on educatng & Improving the service staff.
But it has got a very good looks and power
Thanks for the designers and engineers.
Best of Luck
Thank you & Regards,
Prakash
