You will not be able to buy a Super Splendor's speedometer online as no website is selling it online. The best way to get one is from the nearest Hero authorized service center, which is located at JAIL ROAD (NEAR PWD OFFICE), PO- RADHAKISHORE PUR, UDAIPUR- 799 120. You can drive directly as it is 50 kms from the city of Agartala or even ask your service center representative to order a part from them. You can call them for further information at 09862527303.
