This tunner is well worth it dif more then I expected! Well worth it definitely recommend to anybody with a klx300

This fuel controller works perfect on my 2020 KLX 250. It was easy to install and there is a quite a boost in performance. This also comes with the O2 Sensor Bypass. Package came a week earlier than stated. I would 100% recommend this product!

This works well for my aftermarket exhaust and air filter lid delete.

Works amazing on 2018 klx250. Bought in pa. Put on aftermarket exhaust and removed air box lid. Used the tune info from the product website and it’s is a big difference.
