![]() What you need to know about an exhaust upgrade You should get a little better throttle response, but it will definitely be louder. Just remove the end cap and take off the baffle. You can remove the baffle to open it up a little bit. The downside is that it’s heavy and it restricts some power. It also has a USFS approved spark arrestor so you can legally ride on state trails. The stock exhaust is pretty good on the CRF250F, and it’s definitely quiet, making it a good choice if noise is a concern. This will certainly help when you add an exhaust and get a fuel tuner. You can cut out a section on the top of the air box to allow more air in. This also chokes it from getting enough air when you want to get the most power. The stock intake is sealed up very well to protect the airbox and air filter from water entering. It’s much better than stock, but there’s still no damping adjustment externally. You still won’t have any external adjustability other than the sag/ride height.įor a much more expensive upgrade, you can send your shock to Race tech, as Rick Ramsey did with his CRF250F. It’s a lot of work, and it won’t get huge gains. If you’re extremely mechanically inclined, you can take apart the stock shock and opening up the valving to make it flow more. When you hit the second bump it will compress even more and then when it rebounds it can throw you forward unexpectedly. A stiffer spring (Amazon) will help if you’re a heavier rider, but it won’t completely fix the problem if you’re an aggressive rider.īBR Heavy Duty Shock Spring Rear shock upgrade So, if you hit two consecutive large bumps, the shock will compress and won’t have enough time to fully rebound. This is because the rebound damping is too slow. It’s fine if you’re a beginner or casual rider, but once you start riding faster on rougher terrain, you’ll start getting bucked around. The rear shock is probably the weakest link because it can be dangerous and is harder to adjust or replace. With that said, the XR400 forks are popular on the CRF230F and XR250 as an upgrade, so maybe someone will figure out an easy way to swap them on the CRF250F – it’s probably a simple mod on the triple clamps to fit. ![]() Unfortunately, the CRF250F is so new that I have yet to see someone do a fork swap fr another bike, so I can’t tell you all of the required components. That’s why fork or front end conversions are popular among hardcore trail bike owners. With limited technology, there’s only so much you can do with the stock forks. Your stock forks can work quite a bit better, but you have to be willing to install them at least once to find a comfortable setting. It’s essentially a damping adjustment, but it’s internal, which is the biggest drawback. Want to invest more time and money into a conversion project because you’ll be riding this bike for many years? Then a bigger upgrade might be best for you. What’s your goal and what’s your budget? If you just need a little better working suspension for the cheapest amount, then stick with the stock front forks and rear shock. ![]() The first step to suspension upgradingīefore you start trying to swap forks and a shock over from the latest CRF250R motocross bike, you need to ask yourself a couple of questions. This will be uncomfortable and eventually dangerous because the tires won’t stay planted on the ground and you’ll lose control more easily. The stock forks and shock will bottom out and the compression and rebound won’t be able to keep up if the terrain is rough. Well, if you’re a heavier rider or you just want to ride more aggressively at a faster pace than a novice rider, then you’re going to start getting bucked around. The stock suspension on the CRF250F is soft and the valving is poor, but what does this mean? Suspension – Is it worth upgrading?īefore you do any engine or power mods, you need to give the suspension some attention because it’s the biggest safety factor. The CRF 250F makes good torque from idle all the way to about 8k RPM – this means you can lug it and short-shift and still be able to accelerate at a low RPM. ![]() Having a good, broad torque curve makes it easy to ride off-road because you don’t have to keep it revved up at a narrow RPM range. Why? Because you rarely hold the throttle wide open other than the occasional straightaway – you’re mainly going to be in the midrange of the RPM. To start, a CRF250F only has about 20 HP, but peak horsepower means very little in the off-road world. How much horsepower does a Honda CRF250F have? Will it be the fastest bike or be able to do well on the motocross track? No, but it’s simple, reliable, easy to ride, and just plain fun to ride a “slow bike” fast. ![]()
