Honda CRF300L:
Balance is the key when riding any motorcycle. And we’re not talking about just balancing on two wheels: We’re talking about the balance between size, weight, power and handling that makes some bikes great—like the new Honda CRF300L. Based on our previous CRF250L, for 2021, it gets a larger engine with more torque and a whole host of chassis and suspension refinements. What you end up with is one of the best-balanced bikes ever for on- and off-road use. Perfect for weekend trail rides, it’s also among the best choices ever for commuting or urban transportation. And if you’re looking for a version with a windscreen and Dakar-inspired bodywork for a little more weather protection, make sure you check out our new CRF300L Rally.

Hello my name is Andrew, My family and I love powersports. Just something about the feel of freedom and power you get from a bike or ATV. On this channel you will find content for the Honda 300L as well as our journey we take together in the world of power sports.

I would love to upgrade to the stage 1 ECU for my CRF300l, in order to compliment the RS4 Yoshimura exhaust system, D&N air filter and airbox modifications, but 550 Performance want £650 for a UK order. I feel this is extortionate for 3 Nm of torque and a 12% increase in power gains. If it was £200 I’d be tempted! 😊👍

Always disconnect your negative battery cable before unplugging or plugging in an ECU! Reconnect once finished.

[georgecook]

In terms of percentage change, how much did your fuel economy change after you upgraded the ECU?

great video brother! I didn't get a CEL for even a second🤔

**Ok guys I have an update 2 things have come to my attention.
1.) A commenter Cyber Gasty pointed out US and thai ECUs are different form European ECUs, so you will have to reach out the 550 to see if they have exactly what you need.
2.) it seems 550Performance has updated/changed pricing. I do not yet have the confirmed pricing, I will update you guys when I the new information. I also wanted to include a copy/paste of my conversation with 550performance below. I wanted to be clear and transparent where I came up with my idea of the pricing named in the video.

"550Performance:
We do also offer core ecu’s as they are in stock. This helps speed up the process and minimize the down time. We charge $149.99 for them and will refund $129.99 if the core is returned.


You sent(MotorcyclesOffroad)
ok so you send it out and the person has x amount of time to send their ecu back to you?

550Performance:
I haven’t implemented anything strict in the return time since it is beneficial to get ECUs back.

550Performance:
So if a customer wanted to return a core a year from now I would likely accept it.

You sent(MotorcyclesOffroad)
So you are only making 20$ on something like that?

550Performance:
Yeah, basically covers the fee associated with the process. We offer it solely to facilitate the sales of the tunes"

Sorry dude I don’t do anything on fascist book.

What stage tuner did you get? Also, did you need to do any other work to your bike to use the tuner?

[cryptowelder]

i am in Canada and want to send mine in and its gonna be over $300CAD with boarder charges and new one reaches $500 i am almost to point buy the tuner from dino jet. if there cheaper way for Canadians let me know

[francesboy]

How do you think this bike stacks up to the rally version? Do you think the larger tank and wind protection justify the increased cost and seat height? Who do you think the Rally is for?

[justinbedell]

Hi there. After making the ECU mod, what's your mpg like?

[Jonathan-gztu]

Does this address the extreme heat from these bikes? How about the jerky throttle?

[bryananderson]

I know nobody cares about this but I wonder how much mpg you lose with these modifications.

[MotoSly]

to bad, us european's can't use this ecu.

[RedCAMG]

I sent in the ECU ‘s for both of mine and it was $125 each. I did the Rally first so I could roll race against the 300L. The 550 tune walked the stock with equal rider/bike weights every time. For some reason the 550 tune on my standard 300 is even more pronounced than the Rally’s
Definitely money well spent!

[CyberGasty]

Just a note for Europeans who watch this vid. It is not possible with European ECU, it works only with Thai and US (they are almost identical), smaller in size and connection is different.

[andrewo]

I just received my ECU from 550. All i need now is the bike! March delivery Down Under and can’t wait.

[JohnnyBoy]

I'd be interested in the stock improved map. Maybe you can try that out and see if it's worth it? I wish there were aftermarket exhausts that are as quiet as the oem one otherwise I would get one.

Love your content and looking forward to what's coming next!

[simonbravo]

@MotorcyclesOffroad Thanks so much for your content. Q1) Is the RS-4 exhaust much louder than stock? Q2) Did you leave the spark arrestor in? Q3) Do the 550 needs a different tune for with and without the spark arrestor?

Hi does your electric FAN come on more often with the 550 ECU 91 Tune on your 300L ?

[Dustytrailzzz]

Sorry I am late to the party or missed an updated video, but have you have any reliability issues with the 550 ECU upgrade since you made this review?
