REP Linkage System (2023 Honda CRF450R)

I can guarantee you that there is NO ONE out there that wants the Honda to have comfort as much as I do! I have spent many years purchasing Hondas (2005, 2006, 2008, 2012, 2017). I have spent A LOT of my own money on Hondas only to be let down by the chassis comfort…

Talon Raptor Clamps Review (Honda CRF450R)

First off, Talon saw a mass saving of 181g (approx. 0.4lb) over the OE 2022 Honda CRF450R Triple Clamps which is not a he deal to some but weight is weight. To achieve this, Talon has obviously carried out some heavy optimization in-terms of stiffness to weight, as you may guess by the through-hole lightening!…

Twin Air Power Flow Kit (2023 Yamaha YZ450F)

If you want to get rid of that plastic air filter cage system that sometimes doesn't seal all that well on the 2023 YZ450F, go with the Twin Air Power Flow Filter Kit. To me the Twin Air YZ450F PowerFlow kit is the best all-around filter system for the YZ450F airbox. Why? With this kit,…

2023 Kawasaki KX450 Pro Circuit Ti-6 Muffler System

When you think of muffler systems for the Kawasaki KX450, you think of The Pro Circuit Ti-6 muffler system. I have tested a lot of different mufflers for the KX450, but what does the Pro Circuit system bring to the table for the money? The PC Ti-6 system will set you back $1270.00 and will…

Honda CRF450R Hydraulic Clutch Improvement?

I stumbled on this via Johnny and Preston Campbell but thought it was a good mod to let you all in on. The 2023 Kawasaki KX250/450 master cylinder kit works on the Honda CRF450R and it makes the clutch action as well as the pull so much better! As you know the stock Honda clutch…

FCP Engine Mounts: 2023 YZ450F

I believe in aftermarket engine mounts when they are needed and to me (yes, this is an opinion) last year’s 2022 YZ450F didn’t need aftermarket engine mounts. However, when I swung my leg over the 2023 YZ450F, I thought this chassis could use some sort of engine mount to help with some stiffness that I…

2023 Yamaha YZ450F Optional Yamaha Power Tuner Maps
