O2 (Oxygen) Sensor Eliminator kit OSE-411 (see fitment list)

The O2 Sensor Eliminator Kit by SmartMoto replaces the factory oxygen sensor in a motorcycle's exhaust. The kit allows the bike's ECU to bypass the limitations of the oxygen sensor system and use the installed air-fuel map. This results in improved throttle response, smoother power delivery, and more torque available in the low and mid RPMs.

This kit is designed for motorcycles that follow older emissions standards, such as Euro 2, Euro 3 and in some models up to Euro 4.

Motorcycle manufacturers install the oxygen sensor system to achieve stoichiometric air-fuel ratio. This is good for emissions but converting a bike for trackdays or off-road use means you need to maximise its performance. However, removing the oxygen sensor system triggers an Fi error.

SmartMoto Complete Sets brings an O2 Sensor Eliminator Kit that combines the electronic eliminators and the exhaust plugs in one convenient plug and play package. This results in complete removal of the oxygen sensor system without encountering any Fi errors or performance issues.

Key Features

  • Improves throttle response, offering smoother power delivery and more torque in the low and mid RPMs.
  • It supports Fi tuning modifications such as the Power Commander or ECU remapping which require the removal of the oxygen sensor.
  • Supplements the installation of aftermarket exhaust systems that do not have an oxygen sensor port.
  • Can be used to replace a malfunctioning Oxygen sensor.
  • Plug and play design - no wiring modification is required.
  • The kit contains the number of eliminators and exhaust plugs required to bypass the o2 sensor system on one motorcycle.

Love these
Size: 18-24 Months Infant, Color: Grey
These are awesome! My 15-month old wore these everywhere on our trip to Mexico. He scuffed them up quite a bit, but other than cosmetics, they're holding strong through sand, sprinklers, and general gallivanting around. They are super easy to get on, which also makes them easy for him to pull off. But as long as he's busy running a muck, he forgets they're even on his feet.

Sizing is off, send me free pair!
Size: 3-4 Years Toddler, Color: Navy, Size: 3-4 Years Toddler, Color: Navy
Sizing is off. I’m very frustrated. I ordered it to Costa Rica thru shipping company in Miami, which takes about 3 weeks to deliver and + shipping fee that they apply (20$) I spent time and checked the size guide. According to the size guide, I ordered “3-4 years old” which supposed to be 16cm from heel to toe) the pair I ordered ended up being 17cm! My baby’s feet are 15cm, I was planning to get 16cm for him to grow into it, but 17cm is too big. The shoes it self looks good, the leather is very soft and nice. I’m not sure how durable they are. Ordering first time from this brand. I ordered 2 pairs of shoes from a similar brand and liked it. They just didn’t have the size I needed. Although, the leather the previous brand uses for shoes seems much thicker. Again, I don’t know how durable “Dooty Fish” but I like how soft on skin they are.

Wide and flexible
Size: 18-24 Months Toddler, Color: White
Very cute I love the width and flexibility of the shoe 18 to 24 month is a bit too big for my 18 month old and she generally wears a size 6 1/2 shoe. I’m going to try the smaller size.

Don’t buy
Size: 12-18 Months Infant, Color: Navy
Cute little shoes but I would not recommend people buy these. The elastic broke on both shoes within a month. And they cannot get even a tiny bit of water on them. (Which is impossible with a toddler) If they do get wet the bottoms become dangerously slick. I wanted to get nice little barefoot shoes that I could use as hand-me-downs for future kiddos but these were not it. Horrible quality and not worth the money.

Quality control?
Size: 6-12 Months Infant, Color: Navy, Size: 6-12 Months Infant, Color: Navy
These were true to color (in blue) and are a cute design, however we received a pair that was oddly mismatched size-wise. They were both 6-12mo, however one moccasin was visibly larger and wider than the other. They were both too big for my 7mo old, but even when he'd grow into one the other would be much too large so we returned. Too bad because these would have been perfect if the quality control was there.
