Hopefully you have already seen this on the Radical website or on FaceBook. I feel very honored that Radical has asked me to be their first every Radical Historian. 🙂 I truly enjoy interacting with...

Plenty do in the UK without any issues. The charging system will cope with it fine so no problems. You have to be on top of the system as Lithium does not like being discharged (like a failed charging...

FYI - a couple updates on some tools. Found a great source for the special clutch 8mm bleed tool, much cheaper than Snap-On. As for the very difficult 3/4" nut on back side of rotor drive pegs on ...

@kskins1, as David said, the Racing Radios setup using the CM300D seems to be what most people are using and everyone I talked to is very happy with it. The CP200D is great for the person in the pit....

The 2022 sr3 and sr10 offer a halo now "Available on a Radical for the first time, is an optional halo. Well-known in open-wheel motorsport, the safety structure sits above the driver’s head to protec...

Charley gave solid advice. I'd like to add a few things in case anyone else comes in to read this. Repairing cracks in a chassis should no necessarily be a deal breaker. Now if they are coming up eve...

I drove today. Started cold at 22.5, and hot they were over 26. I could tell a noticeable grip difference when I lowered them to 22 hot. Had some guys at the track recommending 17-18 cold. Seems l...
