WINNING STARTS WITH THE HOLESHOT.
What does it feel like to win? What does it sound like? What does it take to win? Motocross isn’t a sport for the timid. When you show up at that starting gate, both you and your bike need to be ready to grab the holeshot and hang on to it until the checkered flag. That’s why Honda is determined to give you the best bike in the 250 class, the all-new 2018 CRF250R. Major upgrades everywhere, including a new DOHC engine featuring increased power and higher redline, give you the advantages you need and make the CRF250R an absolute holeshot machine.
Features may include:
Not only are the CRF250R’s valves bigger, but they lift higher too, from 9.2mm to 10.5mm intake and from 8.4mm to 9.5mm exhaust. That’s a huge boost, and really helps the CRF250R breathe for more power.
We bumped up the valve diameter on both the intake and exhaust side, from 30.5mm to 33mm on the intakes and from 25mm to 26mm for the exhaust. Combined with the higher lift, the twin-cam CRF250R flows a lot more, especially at high revs when you’re wicking it up.
With our better-breathing DOHC design and the new big-bore/short-stroke engine, the CRF250R’s rev limit jumps an additional 900 rpm. Peak power and peak torque are also up, and the horsepower peak is increased by another 2000 rpm.
By lowering the rear shock mount on the frame, the new CRF250R benefits from both a lower center of gravity (cg) as well as gaining chassis stability.
The 49mm Showa® fork features a conventional spring design that helps increase the CRF250R’s front-suspension precision, handling and feel. The 39mm piston diameter and 25mm rod diameter guarantee a plush feel and supple action.
Shortening the CRF250R’s swingarm helps make it lighter, and also helps give the bike better rear-wheel traction, important considering how much more power you have on tap. The new design also reduces the bike’s unsprung mass.
The 2018 CRF250R uses an all-new double-overhead-cam (DOHC) engine layout with a unique finger-follower rocker design. Together with the rest of the engine’s new architecture (bore and stroke, intake tract, piston, and more), you get more power and a higher redline.
Light is right when it comes to a high-revving engine’s reciprocating masses. That’s why the CRF250R gets titanium intake and exhaust valves. Plus, the valve angle is reduced to a super-narrow 20.5 degrees (included). Ovalized valve springs and long-wearing Diamond-Like Carbon (DLC) treated finger rockers complete the package.
The new DOHC cylinder-head design let our engineers straighten out the CRF250R’s intake and exhaust tracts. The intake is shorter and just about arrow straight, and the exhaust flows more efficiently too. No athlete’s going to win a sprint if he tries to run while holding his breath, and it’s no different with your bike’s engine. You’ll experience both more power and better throttle response.
Blending the new CRF250R’s body panels does more than just make the bike look smooth, fast, and stylish. It also helps you move around on the bike while riding. Nothing wrong with smooth, fast, and stylish, though.
With the all the time you’ll be spending in victory circle, you need to look your best. The new CRF250R has you covered. O
