Buy the chain size your bike uses. For a Coleman CT200U or BT200X, the YOXUFA 420 chain set is the one we would buy: a 90-link main chain, a 42-link jackshaft chain, a breaker and a tensioner, with a 90-day warranty (per the Amazon listing). For #35 bikes like the Coleman CT100U, the RZEOZU #35, 140 links adds a tensioner and fits sprockets up to 75 teeth.
Coleman's CT200U owner's manual sets chain slack at 1/2 to 3/4 in (15 to 20 mm) and says to lube the chain before each ride. Picks were compared on size, link count, fitment and what comes in the box.

Which chain size do I need?
Read the size stamped on a side plate, or measure the pitch: #35 has a 3/8 in pitch (LUPING and AZSSMUK list 0.375 in), while 40/41 and 420 chains have a 1/2 in pitch. Coleman's 196cc CT200U and BT200X use 420; smaller Colemans like the CT100U use #35. A torque converter kit ships with a 10T sprocket for 40/41/420 and a 12T for #35.
| Bike | Chain | Pick |
|---|---|---|
| Coleman CT200U, BT200X | 420 (90 + 42 links) | YOXUFA 420 |
| Coleman CT100U, CC100X | #35, 140 links | RZEOZU or CILOYU |
| Converter swap, long frame | #35, 160 links | LUPING or AZSSMUK |
Setting chain slack
Coleman's CT200U spec is 1/2 to 3/4 in (15 to 20 mm) of slack. Loosen the axle bolts, turn the tension nuts on both sides (clockwise tightens), retighten the axle bolts and re-check. Full steps: how to adjust a mini bike chain.
Lube and inspection
Coleman says to clean the chain with chain cleaner and lube it before each ride, and to inspect for wear, rust, binding links and tension. A worn chain can mean worn sprockets: look for worn, broken or damaged teeth and loose sprocket nuts.
What to skip
Skip guessing the size, skip reusing a stretched chain on new sprockets, and skip adjusting with the engine running. Lift the rear wheel on a dirt bike stand to spin it while you check slack.
