aRacer RC Super 2 ECU: (2019+ CRF110)

The aRacer RC Super 2 for the CRF110F is now available! Time and time again, aRacer has proven to provide riders with game changing products that guarantee an increase to their overall bikes performance. This RC Super 2 has new added features including wireless monitoring that is accessible through the aRacer mobile app. With this new feature, you're able to stream any data from your bike to your phone in real-time.

ARacer RC Super 2 is a complete engine management system that allows you to make all adjustments via a laptop. Tuning could be done on a dyno (highly recommended) or safely on a track or even a backroad/street using a wideband o2 gauge and sensor with the autotune function like the AF1/AF2 that we sell separately. 

The aRacers mobile app allows all complete monitoring your bike on the go. Allowing for features like Data Log, where you can now log and view your ride or race to make proper adjustments via your laptop. aRacer has made it easy to adjust and view your engine details. This does require the aRacer iLink Calibration Cable. The RC Super 2 has made several improvements including higher accuracy and faster computing power. This is key to providing the most detailed information for adjustment and easier to obtain a stronger AFR. It also works with their all-new knock sensor! This will provide more tuning capabilities with timing. This is the only model that can currently run that sensor. If you have any questions please contact us.

In order to use any additional modules aRacer 1 to 4 Cable is required.

Now comes with bLink with improved Bluetooth Phone connectivity.

CRF110 rocket exhaust+RCM5

Absolutely a game changer, I usually run straight t4 in my pitbike because it sips fuel and I love my pitbikes so i feel bad when i put pump gas in them. I'm telling you this because with the stock ecu it runs so lean you can barely smell the race gas, with this ecu, no adjustments just the flash for stock bike it smells much more like my 250f, which was the first thing I noticed. the rpm limit increase from 9800? to 10k feels like each gear is 1.5xish as long with the combination of the extra power the bike makes on this ecu. The rev limiter is way cooler than the stock one. I share my pitbike with my little sister, once upon a time she whiskey throttled into a tree and now only rides in the grass, with this ecu i can set the rev limiter extremely low to make the bike much slower in a situation where she freezes up WOT. I still have no idea what im doing when it comes to tuning it but i used the fuel base and fuel acceleration to experiment and I have to say every small adjustment makes a noticeable difference, feels like a completely different bike with just the RCM5 and rocket exhaust
