Fitting a Levocirator on a Specialized Turbo Levo — anything to worry about?

Is there any reason to be concerned about ins a Levocirator on my Levo?

@Greg Watts

Hi Poho,

Short answer: no real cause for concern, provided you understand what it is and which Levo you're fitting it to.

The Levociraptor (built by @Levociraptor / PaoloBLEvo) is a small inline module that sits on the speed sensor cable. It doesn't reflash your motor, doesn't touch the firmware, and doesn't leave any permanent trace — unplug it and the bike is back to stock. That's why it's been considered the "safe" tuning option on Brose-powered Levos for years.

Things worth knowing before you fit one:

• Compatibility — the original module covers 2019–2020 Levo and 2020 Kenevo. For Gen 4 (April 2025 onwards) there's a dedicated Levociraptor Gen4 with its own speed-sensor cable and BLEvo Smart Power support. Make sure you're buying the right variant for your bike's generation.

• Warranty — Specialized can read tuning activity off the motor's logs at service. Standard Gen 3/4 warranty is 2 years; a tuned bike presented for a motor warranty claim is very likely to be refused. Remove it before any dealer visit and you remove most of that risk, but it's not zero.

• Mechanical wear — you're not increasing motor power, you're letting the motor keep delivering it past 15.5mph (or to whatever derestricted limit you set). The motor itself doesn't care; your drivetrain, tyres and brakes will wear faster because you'll ride faster for longer. Chains especially.

• Legal — derestricting takes the bike outside EAPC rules in the UK. Off your own land it's technically a motor vehicle requiring registration, insurance, etc. Most people use it on private land or accept the risk. Your call.

• Installation — straightforward on Gen 4 with the supplied cable; on earlier Levos it's a sensor-cable splice. No soldering required on the current kits.

• Known gotchas — none specific to the Levociraptor itself, but if you're on a Gen 3 and ever do a firmware update, pair/unpair carefully. @Rob Rides EMTB documented Garmin sensor pairing causing Gen 3 firmware updates to fail mid-flash — worth keeping things tidy around update time. → view post

So: technically benign, mechanically benign, legally and warranty-wise the usual tuning caveats apply. The community track record on PaoloBLEvo's kit is strong.

Which Levo generation are you fitting it to, and are you after speed derestriction, the BLEvo Smart Power features, or both? Happy to get more specific.
