•Tuning session with real engineer: every customer is getting private remote programming session over the phone with one of engineers - they will be able to connect to your controller remotely and will double check have you self installed all right and will set it up safely up to your riding and gearing settings.
•Heatsink mounting kit: we have engineered & cnc machined our own custom heatsink for the ASI controllers to mount it directly on the SurRon. The heatsink will cool down your controller unit significally if thermal paste during installation process will be applied. The heatsink protects your controller from direct contact with stones & dirt - we including side covers and top rubber mudflap to prevent water integration as much as possible.
•Electric “Alta” throttle replacment : Original OEM SurRon throttle is really jerky and has no controll at all whats why we are including “Alta” throttle replacment as when its paired with the ASI controller it gives you an outstanding modulation and full rev controll. Everyone remembers legendary Alta motorcycle which been bought by Harley Davidson - well they been using same throttles on them Alta builds as we are using on our EVF BAC controller kits.
•Custom wirring loom: Our wirring loom it’s different when others. Made in-house by our electricians it benefits from direct throttle connection to the controller loom solving out most common problem - watter in the throttle plug making bike non working as originally your throttle plug is located under bashplate and connected the oem surron wirring loom.
•EggRider Display: It’s a high quality LCD Bluetooth display which has an app for Android and iOS and you will get full functionality with it. You will be able to switch between 2 differently programmed modes up to your preferences and choose to have power levels - 3 or 5 on each mode.
•Install brackets: You will get aluminium mounting bracket which you will attach to your SurRon frame panel and when you will mount our heatsink with the BAC controller slided in and secured.
•Phase extension cables

Which controller should I get?
The BAC4000 controller in most cases is more when enough for majority of users ±90%. But if you are living in a hot climate area or looking to use your kit only on road application running full speed constantly when the BAC8000 will suit you more. Our race personal bike is equiped with the BAC4000 and 72v battery with the big wheels and frame extender and we are not able to push the bike over it’s limits. However SurRon motor is 18kw PEAK capable and you want that maximum performance once again you are looking for the BAC8000 when.
