With its low seat height, modest size, and four-speed transmission with automatic clutch, the CRF110F fills an important entry spot among Honda’s family of off-road bikes. The CRF110F was originally introduced in 2013, replacing the CRF70F and adding quite a few new features to the table. At first glance, you would think why did it jump from a CRF70F to a CRF110F… Once upon a time, a 110cc bike was a machine for adult-sized riders with some experience in the saddle. Then Honda rethought the situation. Sure, small engines make sense for smaller riders, but small engines also can mean narrow powerbands. Why not build a bike that combined the light weight and low seat height of a beginner bike with an engine that’s more beginner friendly? The CRF110F’s engine size makes it easy for our engineers to tune in a super-wide torque spread and easy-to-access low-rpm power which is just what a novice wants and needs.

The biggest additions aside from a slight bump in horsepower and torque comes by the way of a new 4-speed transmission and electric-start whereas the CRF70F only packed a 3-speed transmission and was kick-start only.  The 109cc powerplant is tuned to meet the needs of those new to riding, and with a throttle-limiter feature, it offers parents additional tuning options so you can restrict the speed for your kid on the CRF110F so they can’t go wide-open. Also, the CRF110F features  race-inspired styling evocative of the awesome CFR450R and CRF250R motocross bikes so that way it looks like what your kids will see on TV that the pros are racing.

What does the “automatic clutch” on the CRF110F mean exactly? The automatic clutch means you don’t have to worry about using a clutch to ride the machine. You do still have to change gears though and that’s where it confuses some people but thanks to the auto clutch you don’t have to worry about stalling the engine when coming to a complete stop nor do you have to use the clutch to change gears. Just twist the throttle and click up and down with your foot and you’re good to go.

If the CRF110F isn’t the right size for you, Honda offers a multitude of other CRF-F based trail bikes as well as CRF-R & X motocross race bikes. Here are the available options from Honda for 2018:

  • CRF50F
  • CRF110F
  • CRF125F
  • CRF125F Big Wheel
  • CRF150F
  • CRF230F

1. CRF110F Introduction

The youth market for off-road trail bikes / motorcycles is back and growing more than ever, and looks like it should continue to do so for the foreseeable future. These days riding off-road, in trail parks, motocross tracks or even back yards, can be very much a family activity that involves everyone.

It’s also a great, and enjoyable, introduction to motorcycling and readily builds skills and machine control, so useful later on whether out on the road or in competition. For Honda, acquiring young riders early in their careers is a great introduction to the brand, its core values and most importantly, its motorcycles.

  • Engine/Drivetrain
    • Air-cooled single-cylinder four-stroke 109cc engine tuned for the beginning rider.
    • Four-speed gearbox with automatic clutch.
    • Adjustable throttle-limiter screw to match rider abilities.
    • Convenient electric starter with kickstart backup.
  • Chassis/Suspension
    • Low seat height of only 26.3 inches.
    • Handlebar pad.
    • Race-inspired styling evocative of the CRF450R.

2. CRF110F Model Overview

Honda’s CRF110F replaces the extremely popular CRF70F which replaced the old-school XR70 quite a few years back. The CRF110F is aimed at the 8-11 year old age range, and happily accommodates heights between 3.9 foot and 4.7 foot on average and weights between 60-110 pounds. Primarily designed for leisure riding, it also provides a valuable stepping-stone up to more competition-focused motocross and enduro machines in the Honda range.

The CRF110F’s engine offers more power and torque, and also features an electric starter; a brand new steel frame with improved suspension also adds to the ‘big-bike’ feel and performance. With styling inspired by the 2013+ CRF450R, the family resemblance is more than passing, further reinforcing the CRF110F’s appeal.

  • Adjustable Throttle Limiter

Set the top speed on the CRF110F by turning a screw. That helps keep new riders from going too fast, too soon, and lets you match the CRF110F’s power output to the rider’s skill level.

  • Keyed Ignition

You decide who rides and when because you hold the keys. Got your homework done? Good—let’s ride!

  • Electric Starter

Push a button and go—that’s how easy it is to get going on a CRF110F. Starts after a tip-over are a snap, and the push button means no frustration if junior accidentally stops the engine.

  • Four-Stroke Engine

The CRF110F’s dependable four-stroke single-cylinder engine offers good performance with a wide powerband—perfect for a wide range of riders including beginners. And because it’s a Honda, you know it’s reliable, too.

  • Automatic Clutch

There’s no clutch lever for new riders to master, and that means no stalling. In addition, the smooth transmission offers four gear ratios. All you do is shift with your foot.

  • Backup Kick Starter

Even if the bike’s been sitting all winter, you still can get going with the CRF110F’s kick starter. It’s easy for you to use, and it helps insure that your day of fun doesn’t stop.

  • Sturdy Steel Frame & Swingarm

Less experienced riders are hard on equipment, especially when they’re just starting out. That’s why the CRF110F uses a strong, steel frame and swingarm that are built to handle the bumps and dings of off-road riding.

  • Tough Bodywork

Riders can be tough on equipment, and taking a spill is a natural part of learning. But the CRF110F can handle it. With tough plastic fenders, tank, and other body parts, the CRF110F is engineered to shrug off the minor dings of the real world.

  • Low Seat Height

It’s important to have a bike that’s sized right for your rider. The CRF110F’s low seat height helps build confidence right from the start. It’s seat height fits nicely between the CRF50F and CRF125F.

3. CRF110F Key Features

3.1 CRF110F Engine

With a bore and stroke of 50mm x 55.6 (as opposed to the CRF70F’s 47mm x 41.4mm) the CRF110F’s air-cooled two-valve SOHC engine now displaces 109cc, rather than 72cc. Horsepower and torque figures rise from 5.03 HP & 3.68 lb/ft tq to 7.2 HP & 6.53 lb/ft tq; power is up 49%, torque 77%. The result is greatly improved performance everywhere in the rev-range, and much stronger and more consistent drive out of corners.

The automatic twin clutch system features two types of independent clutch – one for starting, the other for shifting – that makes changing gears easier and smoother than a conventional system. The transmission now also has four gears, instead of three. The engine start switch is on the right hand side of the handlebar, the engine stop switch is on the left.

A 1.2L airbox (the CRF70F used a 0.25L airbox) provides the much greater airflow that the larger capacity engine requires. The exhaust muffler cover is all new; partly for aesthetic reasons but also for improved protection. For more reliable performance digital ignition now gives the engine optimum ignition timing.

3.2 CRF110F Frame / Chassis

To make best use of the CRF110F’s extra power and torque a new chassis was required. The new steel backbone frame and swingarm blends a high balance of rigidity with a certain amount of tuned flex, allowing the rider to fully exploit the engine’s capabilities. The frame also incorporates safety covers at heat points, and carrying handles for easy transport.

The suspension has been completely uprated, for better traction and stability. The telescopic front fork diameter is 31mm, 4mm larger than the CRF70F and has 100mm of travel, while the rear shock absorber features a 28mm piston damper, up 7mm, with 3.54 inches of travel. Drum brakes front and rear provide ample, and measured braking force. The front wheel size is 14in with a 2.5 x 14 tire; the rear 12in with 3 x 12 tire.

A completely new body kit, with echoes of the CRF450R’s ‘triangle proportion’ gives the CRF110F a crisp and modern appearance. The newly designed chain cover looks great and with the addition of a handlebar pad aids safety. Wide-set footpegs increase control, and the redesigned kick-starter is easier to use. The 2018 CRF110F seat height is 26.3 inches, 0.2 inches taller than the CRF70F – but the lowest in class – and the wheelbase is 7mm longer at 42.9 inches. Fuel capacity comes in at 1.1 gallons, and a curb weight of 163 pounds.
