Remember Slater Skins? Yeah, the Blue Buffalo Supercross Team that had the complete signage/coverings across their bikes was John Slater’s brainchild, but most recently he has started to offer air box covers for late model YZ-F’s that increase airflow. We all know more air equals more power, but how does it relate to the track?…
If there is one thing I can complain about on the Yamaha YZ450F, it would be that the ergos are a little weird compared to the other brands. When sitting, the Yamaha feels like the pegs are high and not far enough back for my 6’0 long legged frame. I scoured the land for a…
The average shootout format seems to be an outdated model to me. Don’t get me wrong, I like doing shootouts, as well as viewing their rankings after all is said and done, but is it really telling you, the potential consumer, what you want to know or is it more of a scene on the…
We have come across a couple more maps that we thought worked well in the 2020-2021 YZ450F. These maps feel completely different from each other, but if you’re looking to change your engine character a little, try either one of these maps for your desired delivery.

When it comes to handlebars I am a pain in the ass. The height, width, rise, and position is very important to me between each bike that I test. I find that you can’t run the same handlebar bend on every bike, even though I like a bend on one bike, sometimes it doesn’t feel…
The Yamaha YZ450F comes with the Yamaha Power Tuner App that allows you to change the parameters of the bLU cRU’s ECU settings. It allows the consumer to customize their YZ450F power delivery, so that they can enjoy a more friendly power character or a more aggressive type of delivery. While this system works very…
My 14 year old son Aden has been going back and forth between two different colored 125’s, but has seemed to take a liking to the YZ125 the most lately. I decided see which simple mods could help this Yamaha YZ125 two stroke the most in order to get him some extra ponies. These modifications…
