550cc - Honda CRF450R

Swapped this into my 2009 CRF450R and the bike fired right up with no hiccups, the 550cc flow is dead-on for stock tuning. The fitment is snug and the connector clicked in clean, which I wasn't expecting after wrestling with other injectors. Solid upgrade for the price.

The 550cc flow rate matched the stock specs for my 2009 CRF450R perfectly, and the install was a direct swap with no wiring headaches. Bike’s been running clean and crisp through the whole rev range since I put it in about 300 miles ago.

My CRF450R was idling rough and popping on decel until I swapped in this 550cc injector. The 550 cc/min flow rate smoothed everything out immediately, and it bolted right into the 2015 model without any fuss.
