Royal Enfield Himalayan Maximum Tuning Kit – Euro4 / BS4 Version

Description

This kit consists of a FORGED piston 83.5mm+Rings, a honed cylinder paired with this individual piston, a full gasket set and a 16 teeth front sprocket (for higher top speed and lower rpm at higher speeds).
We also throw in a set of aluminum swing arm bearing plugs. The gasket set includes one foot gasket, one metal head gasket and one exhaust gasket (copper ring).

Then we add the HT-b performance camshaft and our own “Red Box” ECU for which you can download map files free of charge from our site.

Find more detailed information on the parts in this kit on the respective product pages please.

Note: If you want to use this kit you likely also want or even need to make modifications to your air intake (free flow air filter) and exhaust.
