Royal Enfield Himalayan Maximum Tuning Kit – Euro4 / BS4 Version

Description

We will not re-stock this BS4 specific BB set due to diminished demand for BS4 type Himalayan parts.
But you can order it and we will then get the RED ECU from our supplier for you.
This will add approx. one week to the delivery time.

This kit consists of a FORGED piston 84mm+Rings, a honed cylinder paired with this individual piston and a full gasket set.
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 forum 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.

Please consider reading the FAQ dedicated to the 477 engine upgrade.
