ASK THE MXPERTS: WHO MAKES THE BEST 4CS FORKS FOR A 45-YEAR-OLD NOVICE?

Earl Shuler is the master of WP 4CS forks. He can make them work like a charm.

WHO MAKES THE BEST 4CS FORKS?

Dear MXA,

I own a 2016 KTM 450SXF with 4CS forks. I hate them, but since I don’t have a lot of money to spend I can’t afford WP Cone Valve forks or the price of converting my 4CS forks with Kayaba SSS internals. I am a 45-year-old Novice rider who weighs 190 pounds. I have enough money to get my forks re-valved, but I only want to do it once; I hear lots of horror stories about 4CS owners sending their forks to two or three suspension companies without success. I want MXA to tell me who to send my 4CS forks to.

Given your age, skill level and weight, we recommend that you send your forks to Earl Shuler Racing (ESR). ESR has a great reputation for fixing 2015–2016 WP 4CS forks. ESR modifies the forks to allow the fork oil to flow more freely from chamber to chamber. They make the low- and high-speed compression damping more progressive and lighten up the mid-speed compression. The rebound is freed up so the forks can recharge quicker. ESR installs new compression base valves into the bottom of 4CS forks. This puts the compression adjuster in the bottom of both fork legs and makes both fork cap adjusters into rebound clickers. The new base valves come with a longer and more tapered adjustment needle that offers a much wider range of adjustment. We see the ESR guys at the track every week testing WP settings and have ridden with their 4CS, cone valve and AER mods. They are plush. For more info about ESR Suspension, call (760) 949-0942. You have to call, because Earl doesn’t have a website, Twitter account or Facebook page.
