2005 crf450r

This is worth the money. It did exactly what is said it would. It gave it a noticeable amount of torque in 1st and 2nd but it really livened up 3rd to 5th. Great buy would recommend.

Does what it's supposed to

I've had the box for about 2 weeks now and so far it's done everything I needed to and then some I'd highly recommend this box for a OEM replacement considering OEM costs well over 400 bucks

Works great

I've had this for about two years now and I've had no problems with it. It does make a difference in power and top speed.

Not so happy....

the big gun rev box I got and installed in my quad did not work for some reason it made my quad run like grud, so I called motosport to see what they can do for me and some guy named Isaac said "it's a electronic device so we can't take it back call the manufacture see what they say".... sweet thanks

Waste of money

i have a 2009 TRX 450er , i plugged this box in and it literally did nothing for me. i felt absolutely no increase in power and my top speed was clocked actually a little bit slower, from 80 to 76. maybe i just got a bad box, but i am not pleased.

Question asked by Ruby520

Question: It shows above that this big guns Rev limitor will work on my 2020 Honda Rubicon TRX520FA6, this does work correct? And if so does it have installation instructions with it? Is it a chip that I can plug-in to the CDI box on my Rubicon or do I solder it?

Answer: I'm not showing that this will work on the 2020 Rincon. Dynojet isnt showing they have released anything yet. Make sure you have the correct ride profiled before purchasing. If it does become available for your machine it will be a simple plug in and will include instructions - No soldering needed.

Question asked by JDxUNBREAKABLE

Question: I just bought an 03 predator 500. Running through some issues with getting it running. I have a starter on the way but if that doesn't work then I'm thinking it might be the cdi. Can I use this to replace the OEM cdi or is this an addition to the cdi?

Answer: That is an addition to the CDI. unfortunately the CDI has been discontinued by Polaris. Your next best bet would be to check out ebay to see if a used one is available.
