2024 Kawasaki KX450 Optional Engine Mounts

To me the Kawasaki KX450 is improved for 2024 but the new green machine doesn't have the compliance or bump absorption from the chassis like the 2023 version does. I appreciate the front wheel feel in corners compared to the 2023 but the new KX is missing a little comfort on initial bump contact and…

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…

Ride Engineering 23.5mm Offset Split Triple Clamps (2021 Honda CRF450R)

I have been looking for some added stability and comfort from my 2021 Honda CRF450R test machine since I got it and although my suspension setting has evolved/improved over time, I still need some compliancy from this machine.

2021 Honda CRF450R Optional Torque Specs

I have spoke about how important the torque specs are on the 2020 Honda CRF450R before, but in a recent test session with the 2021 CRF450R, this statement never became more true. As always I am looking for more comfort out the 2021 Honda CRF450R chassis even though it is slightly more forgiving than the…

Top 5 Money Mods And Top 3 Free Mods (Honda CRF450R)

2017-2018 Honda CRF450R And CRF450RX Engine Mounts

For 2018 Honda went slightly softer on the top engine mounts of the CR450R. This was to give the bike a little more compliancy (straight line stability) on square edge and choppy terrain. However, if you have listened to my podcasts you will know that the 2018 Honda CRF450R can still feel a little rigid…

2018 Yamaha YZ450F Dubach Racing Engine Relocation Kit

The new 2018 Yamaha YZ450F corners much better than in previous years, but still can feel like it has some front tire pushing when there is nothing to bank off of. This is not as drastic a feeling as it was in 2017, but some riders want more front end bite out of the blue…
