2013–2027 Honda Youth Trail Bike
Stock specifications, generation-specific fitment guidance, rider setup, maintenance priorities and carefully selected CRF110F parts for Honda's electric-start mini trail bike.
All Honda CRF Rider GuidesKnow Your Bike
The CRF110F pairs a 109cc air-cooled four-stroke with electric start, a backup kickstarter and a four-speed transmission with an automatic clutch. The rider still changes gears with the left-foot shift pedal, but there is no hand-clutch lever to coordinate.
The major fitment break is 2019. The 2013–2018 bikes use a carburetor, choke and fuel valve; the 2019–2027 bikes use 19mm PGM-FI and a newer chassis and body platform. CRF's Only has confirmed the applicable 2026–2027 fitment carryover, but intake, fueling, exhaust, electrical and body parts still must match the correct generation.
Both generations say CRF110F, but the 2019 redesign changed the fuel system and many surrounding applications. Confirm the motorcycle's model year before ordering an air filter, carburetor or EFI part, exhaust, fuel-system component, plastics, seat, controls or electrical part.
Start Here
Build confidence with correct physical fit, calm controls and a dependable motorcycle before adding speed or aggressive suspension changes.
The rider should be able to hold the bike upright, reach both brakes and the shifter, turn the bars freely and consistently follow instruction.
Review Rider-Fit GuidanceVerify the model year and whether the bike is the 2013–2018 carbureted platform or the redesigned 2019–2027 fuel-injected platform.
Compare Generation-Specific PartsCheck oil, air filtration, fuel, battery, spark plug, chain, tires, spokes, brakes, controls, bearings and fasteners before every upgrade.
Review MaintenanceQuick Reference
The tire sizes and final-drive gearing below are Honda's stock reference for the U.S. CRF110F. Service specifications can vary by model year, so use the exact-year Honda manual whenever a procedure, capacity, interval or torque value matters.
Current-platform dimensions: Honda lists the 2019–2027 CRF110F with a 25.9-inch seat height, 41.9-inch wheelbase, 6.7-inch ground clearance and 169-lb curb weight. Earlier 2013–2018 bikes differ in several chassis and service details. Honda lists DID 420D-86RB as the original-style replacement chain; confirm the installed 14/38 gearing, axle position and required length if the gearing has been changed.

These are useful starting points—not a list of parts every CRF110F needs. Choose the problem being solved, match the rider, and verify the product's generation and model-year application before ordering.
Protection, Controls & Chassis
For a trail-ridden CRF110F, underside protection, solid foot support and a protected shift shaft usually deliver more practical value than engine work. Confirm control movement after every installation.
A formed-aluminum plate that adds coverage beneath the engine for trail obstacles, ruts and debris.
A bolt-on cradle designed to support the lower chassis area on CRF110F trail and pit-bike builds.
A support-and-guard assembly intended to reduce unsupported shift-shaft leverage while adding coverage near the countershaft sprocket.
A wider stainless-steel footpeg platform for riders who want more boot support and grip than the stock mini-bike pegs provide.
Suspension & Rider Fit
Spring changes can reduce excessive sag or bottoming, but they cannot fix worn bearings, a damaged shock, binding forks or a rider who has outgrown the motorcycle. Keep Honda's 132-lb total-load limit in view.
Replacement fork springs for riders and uses that need more front-end support than the stock setup supplies.
A generation-specific rear spring for the original carbureted CRF110F platform.
The later-generation rear spring option for the fuel-injected CRF110F chassis.
Check ground reach, standing position, lever reach, handlebar clearance and room to move before altering seat or bar height.
Airflow, Fueling & Exhaust
A 2013–2018 carbureted bike and a 2019–2027 fuel-injected bike require different intake and fueling parts. Start with a clean filter and healthy engine, then coordinate any intake or exhaust change with the correct fuel strategy.
A washable dual-stage foam filter shaped for the original carbureted CRF110F airbox.
The later-generation washable foam filter for the fuel-injected CRF110F airbox.
A complete exhaust option for the carbureted generation that should be planned with intake condition and appropriate carburetor tuning.
A later-generation exhaust system for the PGM-FI CRF110F platform.
Drivetrain, Tires & Brakes
The CRF110F uses a #420 chain and 14/38 stock gearing. Count both installed sprockets, check axle position and read both tire sidewalls before ordering because previous owners often change these items.
A replacement front sprocket family for CRF110F drivetrain service or a deliberate gearing change.
A durable steel rear-sprocket option for replacing worn gearing or planning a supported ratio change.
A #420 replacement chain that must be sized around the actual sprockets, axle position and adjuster range.
Stock tire sizes are 70/100-14 front and 80/100-12 rear. Inspect tubes, rims, spokes, wheel bearings, brake adjustment, shoes and drums as one wheel-service job.
Service Parts & Information
Both CRF110F generations have electric start and a backup kickstarter, but their fuel and electrical systems differ. Use the manual for the exact year, and diagnose before replacing components.
A printed factory service reference for the listed 2019–2026 fuel-injected models.
A conventional replacement battery application for the carbureted CRF110F generation.
A replacement fuel-pump kit for the PGM-FI generation when testing confirms a fuel-delivery fault.
A model-listed drain plug with a magnetic tip intended to collect ferrous wear debris during normal oil service.
The complete results include universal and generation-specific products. Confirm the exact year, installed configuration and product application before ordering.

Common Questions
Quick answers for model years, generation fitment, rider setup, stock specifications, maintenance and common upgrade decisions.
This guide covers the 2013–2027 U.S.-market Honda CRF110F. The major parts-buying split is between the 2013–2018 carbureted bikes and the redesigned 2019–2027 fuel-injected bikes.
No. The CRF110F replaced the CRF70F in Honda's trail lineup for 2013, but it is a different motorcycle. A part listed for the CRF70F is not automatically a CRF110F application.
Honda changed the CRF110F to 19mm PGM-FI for the 2019 model year. The 2013–2018 bike uses a carburetor, choke and fuel valve. The 2019 redesign also changed the chassis and body platform, so the year matters beyond fuel-system parts.
Yes. The CRF110F has push-button electric starting plus a backup kickstarter. A working kickstarter is useful when the battery is low, but the battery, charging system, cables and fuel system should still be kept in good condition.
No. It has a four-speed transmission with an automatic clutch. The rider shifts with the left foot but does not operate a hand clutch; it is not a fully automatic transmission.
Choose by physical fit, skill and total load rather than age alone. Honda lists a 25.9-inch seat height and 132-lb maximum total load for the current platform, including rider and accessories. An adult who exceeds that limit should choose a larger motorcycle; stiffer springs do not raise the rating.
Honda does not publish one fixed top-speed figure in its owner specifications. Actual speed changes with the throttle-limiter setting, rider, terrain, condition, tires and gearing. Do not use an internet top-speed claim to decide whether the motorcycle safely fits a rider.
No. The U.S. CRF110F is designed and manufactured for off-road use. Registration and equipment rules vary, so adding a light or other individual accessory should not be assumed to make it legal for public-road use.
The stock sizes are 70/100-14 front and 80/100-12 rear, both tube type. Honda's owner information lists 15 psi cold front and rear as its baseline; read both installed sidewalls and follow the exact-year manual and tire-maker guidance.
Honda's stock reference is a #420 chain with a 14-tooth front and 38-tooth rear sprocket, with 10–20 mm chain freeplay. Count what is installed and determine replacement-chain length around the actual gearing and axle position.
Honda specifies an NGK CPR6EA-9S with a 0.8–0.9 mm gap. Follow the exact-year manual for inspection, installation and tightening.
Honda's current reference specifies SAE 10W-30 motorcycle oil meeting JASO MA and API SJ or higher, with 1.1 US qt after draining. Exclude energy- or resource-conserving automotive oils, follow the exact-year manual and verify level with Honda's procedure rather than treating capacity as a blind pour-in amount.
Verify the VIN and year, identify the carbureted or EFI generation, request a true cold start, test electric and kick starting, shift all four gears, and inspect the fuel and intake systems, oil, smoke, leaks, automatic-clutch operation, chain, sprockets, tires, spokes, bearings, drum brakes, suspension, frame, peg mounts, controls, limiter and previous modifications.
Start with rider fit, protective equipment, predictable controls and a safe maintenance baseline. Add underside or shift-shaft protection for trail use, then evaluate suspension support. Save power modifications for an experienced rider and a coordinated, generation-correct build.
