Akrapovic Evolution Muffler System (2020 Honda CRF450R)

This is embarrassing, but I am going to be completely honest here… I think about the Honda CRF450R a lot. More than other machines. I mean I will literally wake up in the middle of the night and think of things to test in order to try and make the Honda chassis calm down a…

Wrench Rabbit Yamaha YZ125 Engine Rebuild Kit

By Michael Allen: Although one of the main perks or being a part of Keefer Inc. Testing is getting to ride the latest and greatest bikes, there are times when you need to have your own bike. I needed my own bike because I was going to race the Los Ancianos Tecate Enduro that is…

FMF Factory Fatty Pipe/Shorty Silencer (2020 KTM 125SX)

Since the delivery of our KTM 125 SX, my son Aden has been riding it non stop. He also has been barking in my ear about getting a pipe and silencer so it “sounds cool”. While I am usually reluctant to add parts to my kid’s bike for the sake of just doing it, I…

2017-2020 Honda CRF450R Clutch Fixes

Do you have a 2017-2020 Honda CRF450R? If so, then you know that the clutch is not the best of the bunch. The clutch gets hot too quick then proceeds to drag/slip during your moto and you’re left with throttle to rear wheel connection loss (aka loss of power/traction). Or how about that clutch lever…

Dunlop MX53 Tire Review

Dunlop recently introduced their new MX53 intermediate to hard terrain tires last week to the media at Perris Raceway. I was excited about the new tire from Dunlop because quite frankly there hasn't been an intermediate to hard terrain tire that I have been over the moon about in a very long time. I usually…

FMF 4.1 RCT Muffler With SX Style Megabomb Headpipe (2020 KX450)

The Kawasaki KX450 was the most improved 450 machine of 2019 and with Kawasaki not changing anything on the 2020 KX450, I wanted to test some new aftermarket parts to see if I could improve on what I already knew from last year’s machine. I knew FMF had two headpipes available for the KX450, but…

Ride Engineering Axle/Axle Block Kit For KTM/Husqvarna

KTM/Husqvarna uses an axle that resembles a bolt with a nut on one end. Although it’s nice not to have to mess with the left side axle block when putting in the axle through the swingarm, it’s not so friendly on the rear end of the bike while you're riding. Why? Because when you’re heavy…

MX V2 ODI Lock On Half Waffle Grips

Lock on grips are all the rage right now. I mean I get it, they're fairly inexpensive, easy to install, and takes literally a minute to install fresh grips and immediately go ride. I have been kind of old school in my “grip ways”, but thought I would test the ODI V2 Lock On Grips…

Works Connection Titan Skid Plate

Written/Tested By Michael Allen: Any dirt bike (be it off-road or motocross) should come stock with a skid plate. Some people may say that for motocross it’s not necessary to have one because there aren’t big rocks and hazards, but I feel that having a skid plate is cheap insurance for the under carriage of…

Tusk Impact Wheelset (2019 Yamaha YZ450F)

Mounting up some hubs/wheels is one of the first aftermarket modifications riders do to their ride. Do all dirt bikes need aftermarket wheels/hubs? No they don’t, but some can benefit from a beefier wheelset (like the Honda CRF250/450R and Yamaha YZ250/450F), so we decided to try the Tusk Impact wheelset and put some abuse on…
