ZForce 800 Trail

CFMOTO ZForce 800 Owner's Hub

The ZForce 800 Trail is the narrower, lighter sport machine in CFMOTO's lineup, running an 800 cc V-twin through the CVTech Trailbloc CVT. It shares fluid specs and service intervals with the 950 almost exactly - same 4.33 quart coolant fill, same 75W-90 transmission oil, same 250 and 400 ml gearcases - but it keeps the older NGK DCPR8E spark plug at a 0.031 to 0.035 inch gap where the 950 moved to a CR8EK. One more distinction matters when ordering: CFMOTO built 800s with both plastic and aluminum clutch covers, and the clutch parts are not interchangeable between them. Check your cover before you buy a clutch kit, or send us a photo and we will confirm it. Service numbers, fitting parts, and job-by-job guides are all below.

ZForce 800 Trail Service Specs

The numbers you need before you start a job — 800 cc liquid-cooled V-twin (2V91W-B), 8-valve SOHC, EFI, 2023-2026. Figures are from the current CFMOTO owner's manual for this machine; check yours if you run an earlier model year.

Maintenance Schedule

Whichever interval arrives first is the one that counts. CFMOTO counts frequent mud, water, sand, dust, heavy hauling or towing, and repeated short trips as severe use. If that describes how you ride, cut every interval below in half.

Where to start

Upgrade Path

Do these in order. Each stage builds on the one before it, and skipping to the end usually means paying twice.

Stage 1

Belt & filters first

A fresh belt and a clean intake screen fix more perceived power problems than any clutch part. Do this before you spend money on tuning.

View part

Stage 2

HELLRAISER primary

The primary clutch is where engagement and backshift live. This is the single upgrade riders notice most on a CVTech machine.

View part

Stage 3

Stingray helix & spring

Match the secondary to the primary. Running a tuned primary against a stock helix leaves most of the gain on the table.

CFMOTO Clutch Kit Buyer's Guide: CVTech vs OmniDrive

CFMOTO uses two different CVT clutch systems across its lineup: CVTech (Trailbloc) and OmniDrive. Choosing the wrong kit means wasted money and poor performance. This guide breaks down which system your machine has and which aftermarket kit you need.

CFMOTO Maintenance Schedule by Model

Every CFMOTO service interval in one place, plus the fluid capacities for ten machines. Which interval actually counts, what severe use does to the numbers, and the jobs owners most often skip.

CFMOTO Spark Plug Service & Gap Reference

Which plug your CFMOTO takes, gapped to what, and why the ZForce 800 and 950 in the same manual use different plugs. Plus what a used plug tells you about how the engine is running.

CFMOTO CVT Belt Replacement Guide

The CVT belt is the most-replaced wear item on any CFMOTO. This guide covers how to tell when a belt is done, the tools you need, the full removal and install procedure, and the break-in that makes a new belt last.
