What Are The Best CRF110 Mods For Adults?

Alright, so you got your Honda CRF110 pit bike, but it’s time to modify it. There’s a lot you can do with your red machine, but a lot of it is just bling or overpriced for what you get. 

So, I want to give you a list of the best mods for your CRF110. Some will get you more power, but there’s other necessary upgrades that make your bike safer and more comfortable, as well as durable.

Stock CRF110F Ready To Be Modified

Let’s face it, if you’re reading this article, then you more than likely have this bike for the sheer fun that it brings. That means it’s going to need to take some abuse. There’s a few things you need to do or upgrade to make it last longer.

So, without further ado, here’s the best mods for your CRF110 that will give you bang for your buck are:

  • Carb upgrade
  • Bars (klx110 pro taper)
  • Tires
  • Fork springs
  • Rear shock
  • Shifter
  • Skid plate
  • Exhaust
  • Big bore kit
  • Pod filter
  • Upgraded levers

Carb Upgrade

Up until 2019, the Honda CRF110 came with a 15mm carburetor. After that it now has a fuel injected system. 

If your CRF110F has a stock carb, an affordable mod that makes a noticeable power difference is upgrading to a larger carb (Amazon). 18-20mm is a good size depending on what kind of power you want and how many other mods your bike has. 

A smaller 18mm carb will be better for low-end torque, whereas a 20mm will be best for top-end or for big bore engine builds. 

Handlebars To Fit You

If you’re an adult, you need to get some taller handlebars or else a 110 will feel really cramped. 

KLX110 bend Pro Taper bars (Amazon) or a Renthal Mini bars are a good upgrade for this bike. They’re taller, stronger, and better looking.

Tires For Confidence

Stock tires are cheap and usually hard, especially if they’ve been sitting for at least a year.

Upgrading to some better tires will give you more traction. More traction equals more comfort and confidence because the bike won’t slide out as easily.

Fork Springs To Aid Comfort

If you’re an adult or are riding your CRF 110 aggressively then the stock suspension isn’t going to cut it.

The stock fork springs are for a little kid, so you’re going to bottom out the forks without much effort when riding. Bottoming out the suspension will eventually damage and break parts, including the frame if you’re really rough on it. 

It will also be unstable to ride if you’re constantly blowing through the suspension stroke. 

An affordable set of heavy duty fork springs (Amazon) is a simple and effective upgrade to make your CRF110 a more comfortable pit bike.

Rear Shock To Replace Weak Stock

The stock rear shock is just as bad as the front forks. Just like the forks, you can get a heavy duty rear shock spring (Amazon) to swap out the soft stock spring. Now you won’t be compressing the shock when just sitting on it!

Or you can upgrade the entire shock for a better performing aftermarket shock (Amazon). The cost is not much more than a spring for a cheaper model. 

Shifter That You Can Shift

The stock shift lever is designed to be shifted by a little kid sized boot. Replacing it with a longer shift lever will make it feel less cramped, as well as being more durable in the inevitable spills while you’re having fun riding with your friends or family. 

Skid Plate That Protects Your ‘Goods’

Pit bikes don’t have much ground clearance, which can wreak havoc if you’re riding over obstacles. Whether it be logs, rocks or coming up short on jumps, the underside of your CRF110’s engine and exhaust is exposed.

One little “oops” moment can bend or break parts and ruin your day, as well as your wallet.

Installing a skid plate (Amazon) will protect your 110 from impacts. It also strengthens the engine and frame because it bolts directly to it.

Exhaust

Time for some fun mods that really wake up this 110 pit bike! An exhaust upgrade is one of the easiest ways to get more performance (and noise) out of your CRF 110.

Cheap CRF110 Aftermarket Exhaust

Just looking for the cheapest pipe to modify your little Honda? Amazon has a PC T4 replica exhaust that fits your 110cc Honda. It’s an easy bolt-on mod and should make a noticeable difference.

The downfalls?

Quality control might not be as good as a name brand exhaust company. Testing may or may not have been done for optimum performance. This means that it’s simply an ‘opened up’ exhaust and is going to be much louder than stock. You’ll gain some power if your carb is properly jetted.

Quality CRF110 Exhaust

Want a higher quality exhaust that is more than just “extra noise”? Yoshimura’s RS2 exhaust system for the CRF110 is good looking, good sounding without being obnoxious, and it sure to give you better performance with proper jetting/EFI tuning.

You also have the option of adding a spark arrestor/insert later to make your dirt bike legal for trail riding.

Big Bore Kit

A big bore kit is one of the best ways to get more torque and horsepower out of your CRF110. It’s close to the same price as an exhaust upgrade, if not less.

However, it’s obviously more involved since you have to replace the stock piston and cylinder.

The BBR 132cc big bore kit is affordable and reliable. If you want more power or need to rebuild the top end on your CRF110, this is an easy decision. Runs on pump gas.

Air Filter For Max Power

Upgrading the intake to get more air through is also important if you want more power. With that said, you must be careful that any intake or air filter mod is done properly and with high quality parts that fit. 

Any leak or improperly installed/oiled air filter will cause dirt to get sucked in. This will result in major engine wear over time. 

Replacing the stock air filter with a better flowing aftermarket filter (Amazon) will allow more air through. The more engine and exhaust mods you do, the more air you’ll need to get sucked through to make the most power. 

Gearing Up For Top Speed

Although gearing changes don’t affect power numbers, they do make noticeable changes in acceleration or overall top speed, depending on which way you go. 

Going down 1 or 2 teeth on the rear sprocket (Amazon) will give you more top speed. It will also make first gear more usable, as in you don’t have to shift to 2nd immediately.

Upgraded Levers

Stock levers on the CRF110F are nothing special, but it’s not really worth upgrading until they break, unless you’re picky. Once you bend or break the stock brake and clutch lever, get some of these aftermarket levers that can take more of a beating and look better.

Best Cheap Performance Package:

Looking for the best bang for your buck? The suspension mods are the first thing you should do before modding for more power. If you don’t, you’re going to be uncomfortable and eventually break parts from constantly bottoming out the suspension.

As far as getting more power, I would upgrade the carb, air filter, get a big bore kit, go taller on the gearing, and an exhaust if it’s in the budget. Doing one thing will make a slight difference, but getting the whole package to work together (especially if it’s properly jetted/tuned) is where you’ll feel some significant power gains.
