Comparing The 300EX To Similar Bikes

To fully appreciate the 300EX, it helps to see how it stacks up against similar trail bikes from Honda:

Honda 300EX Vs. 250EX

As you’d expect, the 300EX has an edge in power over the 250EX. That gives the 300EX a faster top speed. The 300EX is also slightly heavier.

Overall, the extra power of the 300 is noticeable on the trails. But the 250 can still hold its own as a very capable machine.

Honda 300EX Vs. 400EX

When put head to head against the 400EX, the 300 starts to show its limitations. The 400EX churns out significantly more power. That allows a higher top speed on the 400EX.

The 400EX is also just a bit heavier.

So while the 300EX is peppy, the 400EX dominates in pure power and speed. But some riders prefer the 300’s lighter, more flickable feel on tight trails.

Key Features And Benefits

Now let’s dig into the features that made the 300EX so popular:

  1. Legendary Motor: The motor gives the 300EX strong mid-range punch. While not the fastest bike, the 300 motor is super snappy and fun on trails.
  2. Light And Nimble Handling: Weighing in at just around 218 pounds, the 300EX is nimble and easy to throw around on the trail. The light weight makes it less fatiguing to ride for extended periods.
  3. Excellent Trail Suspension: With over 8 inches of travel front and rear, the 300EX has plush suspension that soaks up the trail. The long travel and soft setting helps keep the wheels planted over rough terrain.
  4. Hydraulic Clutch & 5-Speed Transmission: The 300EX was one of the early adopters of a hydraulic clutch system. This gives a light clutch pull and smooth engagement.
  5. Reliable Electric Start: While some hardcores prefer kick-starting their bike, most riders appreciate the convenience of push button electric start – especially when the bike is hot or elevation increases.
  6. Strong Braking Power: Hydraulic disc brakes provide strong stopping power on the 300EX front and rear.

Pros and Cons of Owning a 300EX

Now let’s get into the pros and cons of owning one of these bikes:

300EX Pros

Why Does The 300EX Have Such A Cult Following?

Owning and Maintaining a 300EX

If you’re lucky enough to get your hands on a 300EX, here are some ownership tips:

  • Oil injection – Keep the oil tank full as it lubricates the engine. Check the oil lines for cracks. Pre-mix fuel for added protection.
  • Top end rebuilds – The piston and rings will need replacement more often than a 4-stroke. Rebuilds every 100 hours or so helps maintain peak performance.
  • Suspension servicing – The springs and seals deteriorate over time on those old shocks. A rebuild or swap out for newer suspension is recommended.
  • Carb tuning – Proper jetting and adjustments are needed to keep the carburetor running in top shape.
  • Routine maintenance – Change oil, air filters, plugs, and check chain & brakes as you would any dirt bike to avoid breakdowns.
  • Finding parts – Many parts are no longer available from Honda, but the aftermarket and used OEM parts keep them going.

Some basic mechanical skills go a long way towards owning and maintaining a 300EX. Thankfully there is a strong enthusiast community to provide tips and part resources.

Finding a 300EX for Sale

The 300EX is long discontinued, so you’ll have to scour the used market to find one. Here are some tips:

  • Check local classifieds – You can find 300EXs for sale on Craigslist, Facebook Marketplace, or local forums. Private sellers often have the best deals.
  • eBay Motors – There are often 300EX bikes and parts for auction on eBay. Cast a wide national net to find inventory.
  • Dirt bike dealers – Some dealers resell used models. Their service departments can inspect a bike before purchase.
  • Dirt bike forums – Post on forums like ThumperTalk that you are bike hunting. Members often know of bikes for sale.

  • Honda CRF230F – A newer 4-stroke trail model with electric start and a mellow power band. More reliable and cheaper to own.
  • Suzuki DR-Z400 – A 400cc 4-stroke dual sport. Great for trails while still street legal. More modern engine and features than the 300EX.
  • KTM 300 XC-W – A high performance 300cc 2-stroke for racing enduro. Pricey but with the latest technology and handling.

So while the 300EX itself is being phased out, there are still great modern trail bikes that capture a similar spirit and abilities at a more affordable price point.

Is the Honda 300EX Still Worth Owning Today?

Even though the 300EX is outdated by today’s dirt bike standards, it still delivers an incredibly fun riding experience in the right conditions. There’s a reason it maintains such as loyal following decades later.

For the right person – say an intermediate rider focused on trail riding rather than motocross – the 300EX is hard to beat. There’s nothing else quite like ripping a light, flickable 2-stroke through tight woods and over bumps.

The 300EX suits a niche rider that appreciates the bike for what it is – an old school machine that delivers big grins when ridden within its comfort zone. It brings a purity of experience that’s hard to replicate on more modern bikes.

Sure, it lacks amenities like a folding shift lever or push button start. And electric bikes and turbocharged 4-strokes blow it away on pure power. Yet the 300EX retains an undeniable charm.

It’s also hard to beat that classic look – the iconic Honda red bodywork over a steel perimeter frame. It just looks like a badass trail bike.

So while the 300EX sadly gets overshadowed by faster modern bikes, it’s still a worthwhile machine. There will always be riders craving the light, flickable feel and snappy power delivery of this 2-stroke legend.
