Randy Richardson’s World Vet/2021 YZ250F Experience

#WhatTheHelen It started with a text message. Steve Matthes sent a photo to Kris and me Sunday evening, November 1, of a freshly installed MICHELIN® StarCross® 5 Soft front tire along with the comment “World Vet prep”. Ever being the jokester, my quick reply was; “When do I need to fly in?”From there, things escalated really…

Optional 2020-2021 Yamaha YZ450F Maps

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. Smooth out the herky/jerky low end feel when rolling…

Pro Circuit Link Arm (2020 Yamaha YZ450F)

I have tried links in the past on previous generation YZ450F’s with less than stellar results, but since Yamaha changed the frame on the 2020 machine, I thought I would revisit a link to see if it helps improves the Yamaha’s feel around the track. Pro Circuit's linkage arms are CNC-machined from billet aluminum and…

2006 YZ125 Craigslist Project

By: Michael Allen Although I have access to bikes for testing throughout the year, there are times when it’s necessary (and nice) to have your own bike. In this particular case I was invited to Mexico with the Smith family (as in Malcolm Smith) to race the Tecate Enduro which meant I needed a legit…

2020 Yamaha YZ125X/250FX Introduction

YZ450F GYTR Tall Seat

Yamaha has an accessory division called GYTR and when it comes to accessories for your YZ they have tons to offer. I wasn't quite happy with the “pocket” feel that the stock 2020 YZ450F seat has to it once the foam is broken in, but managed to stumble across the Yamaha Accessories tall seat while…
