The short answer
Buying a chain comes down to two things: the pitch (which you must match exactly) and the length (link count). On these bikes the pitch is model-specific — there's no single "Sur-Ron chain" — so:
- Match the pitch exactly (420, 428, 520, 530, or #25). A 420 and a 428 are not interchangeable.
- Count the links on your old chain where a length isn't confirmed below — chain length can change with sprocket sizes and revisions, so counting your existing chain (or buying the maker's exact replacement) is the safe move.
Below are the verified values. Where a maker doesn't reliably publish a figure, it's shown as —; where sources conflict, that's noted rather than guessed.
Sur-Ron
| Model | Chain pitch | Links | Front / rear sprocket |
|---|---|---|---|
| Light Bee X | 420 | — | — |
| Ultra Bee | 520 | ~96 | 13T / 46T |
| Storm Bee | 530 | — | — / 52T |
| Hyper Bee (14/12) | 420 | ~94 | 12T / 41T |
Notes: for the 2026 / 72V Light Bee X, the maker doesn't publish the link count or sprocket teeth — older 60V Light Bees used a 420 chain around 106 links with a 14T/48T setup, but don't assume that carries to the 2026 bike; count your chain. The Hyper Bee's 12/10 variant uses a 37T rear (which pairs with a ~92-link chain) — check which wheels yours has.
Talaria
| Model | Chain pitch | Links | Front / rear sprocket |
|---|---|---|---|
| Sting MX3 | 420 | — (see note) | — / 44T |
| Sting R MX4 | 420 | — (see note) | — / 44T (48T option) |
| Sting MX5 Pro | 428 | — (see note) | 13T / 48T |
| Komodo | 520 | — | 14T / 53T (trim varies) |
| Dragon | 520 | — | — / 48T |
Notes: the classic Sting MX3/MX4 run a 420 chain, but replacement listings conflict on the original length (104 vs 106 links) — count your chain rather than trusting a single listing. The MX5 Pro is a different, newer chassis that uses a 428 (one dealer spec confusingly listed a 418 chain — treat 428 as correct per the OEM sprocket parts, and confirm). The Komodo's sprocket setup varies by trim.
Segway
| Model | Chain pitch | Links | Front / rear sprocket |
|---|---|---|---|
| X160 | 420 | 112 | — |
| X260 | 420 | 106 | — |
| Xaber 300 | 520 | — | — |
Notes: Segway's support pages publish the X160 as a 420 chain with 112 links and the X260 as 420 with 106 links — unusually clear figures. The Xaber 300 steps up to a 520 chain (link count not published).
72V clones (Light Bee class)
| Model | Chain pitch | Links | Front / rear sprocket |
|---|---|---|---|
| E-Ride Pro SS3 | 428 | ~114 | 14T / 58T |
| Rawrr Mantis X Pro | 428 | ~114 | — |
| Apollo RFN Ares | 420 | — | 13T / 58T (trim varies) |
| Arctic Leopard XF | — (see note) | — | — / 58T |
Notes: the RFN Ares front sprocket varies by trim (11T or 13T) — confirm yours. The Arctic Leopard XF has a pitch conflict: the US parts collection lists a 428 chain while a reputable review reports a 520 — so we won't publish a single pitch for it; verify against your exact model/region before buying.
Razor Dirt Rocket (kids)
| Model | Chain pitch | Links | Front / rear sprocket |
|---|---|---|---|
| MX350 | #25H | 126 | — |
| MX650 | #25 | 132 | — |
Notes: the MX350 (126-link) and MX650 (132-link) chains are not interchangeable — the MX650's is the longer one. This mirrors the 24V/36V split across the whole Razor parts range (see the Razor replacement guide).
The bottom line
Match the pitch exactly — it's the one thing you can't get wrong — then get the length right by using the verified link count where we list one, or counting your existing chain where we don't. Replace the chain and sprockets as a set when they're worn, keep the drivetrain maintained with the chain-care guide, and confirm every value against your exact model and year (see the compatibility guide).

VoltRipper is independent — we don't sell parts and our recommendations aren't pay-to-play. Chain and sprocket sizes are verified against manufacturer and vendor sources and shown as "—" where not reliably published or where sources conflict; they can vary by model year, trim, and region, so match the pitch and confirm the length against your exact bike before purchase. Affiliate disclosure is included on monetized pages, and we're spec-verified/data-driven rather than hands-on until first-hand testing exists.
FAQ
What chain does a Sur-Ron use?
It depends on the model, and the pitch is the part you must match exactly. The Sur-Ron Light Bee X uses a 420 chain; the Ultra Bee uses a heavier 520 chain (about 96 links, with a 13-tooth front and 46-tooth rear sprocket); the Storm Bee steps up again to a 530 chain; and the youth Hyper Bee uses a 420 chain (about 94 links, 12T front / 41T rear). So there's no single 'Sur-Ron chain' — confirm your exact model, match the pitch, and where a link count isn't published, count the links on your existing chain before ordering.
Do Sur-Ron and Talaria use a 420 or 428 chain?
It varies by model, which is exactly why you check. The Sur-Ron Light Bee X and the classic Talaria Sting MX3/MX4 run a 420 chain, but the newer Talaria Sting MX5 Pro uses a 428, and the E-Ride Pro SS3 and Rawrr Mantis X Pro clones also use 428. Heavier bikes go bigger still — the Sur-Ron Ultra Bee and Talaria Komodo use 520. A 420 and a 428 are not interchangeable, so match the pitch to your exact bike and never assume a clone shares its neighbor's chain.
How many links is my dirt bike chain?
Where the maker publishes it, we list it (for example, the Sur-Ron Ultra Bee is about 96 links and the E-Ride Pro SS3 about 114); where it isn't reliably published, the most accurate method is to count the links on your current chain before buying. Chain length is easy to get wrong from a chart because it can change with sprocket sizes and model revisions, so counting your existing chain — or matching the exact replacement your bike's maker sells — is the safe approach. Get the pitch right first, then the length.
What size chain does a Razor Dirt Rocket use?
The Razor MX350 uses a #25H (25H) chain with 126 links, and the MX650 uses a #25 chain with 132 links — the MX650's is the longer one, and the two are not interchangeable. This is the same 24V-vs-36V split that runs through all the Razor Dirt Rocket parts: match the exact model. See our Razor replacement-parts guide for the full battery, charger, chain, and throttle breakdown, each kept separate by model.
