Dirt Biking simply cannot get any better for the pros. “This is what I want and how I wanted,” said Trey Canard. Although he did get a modified version, this all-new 2017 Honda CRF450R is as good as it gets for a dirt-bike. But why is the most anticipated model of the year? What does a dirt bike need to be the best of the lot? Let’s break it down, let’s dismantle and reassemble it from the inside out.
2017 Honda CRF450R Engine:
- Engine type – 449 cc single-cylinder liquid-cooled four-stroke
- Compression Ratio – 13.5:1
- Bore And Stroke – 96 x 62.1 mm
- Induction – PGM-FI (Programmed Fuel Injection), 46 mm Throttle downdraft body
- Valve Train – Unicam® four-valve; 31mm exhaust, Steel; 38 mm intake, titanium
- Ignition – Fully transistorized plus electronic advance.
These stats are gospel to any motocross pro. What Honda has done is provided the 2017 Honda CRF450R with the best possible advancements keeping in mind what a professional motocross biker would want. Ask ten-time winner Akira Narita; he’ll probably vouch for this model more than anyone. He knows what it is all about.
This new Unicam® engine produces 5 HP more and increased turbo-availability throughout the rev-range; simply speaking, this model faster, much faster. Other modifications in the engine providing for the increased power and handling are as follows:
This new engine is placed much lower and more towards to rear for better CG (Centre of Gravity) and rear-wheel traction. Along with this new model also hosts-
- New valve seats and bigger intake valves.
- Redesigned valve springs, oval at the cross-section, providing better top-end.
- Higher Compression Ratio at 13.5, up from 12.5, with newly shaped pistons.
- More vertically arranged intake and exhaust manifolds.
- Cleaner downdraft path for increased efficiency and power.
And these are just the major modifications as far as the engine is concerned.
Handling and Transmission:
One of the most important aspects of a dirt-bike is suspension or ride quality. And, after the previous ones, there are added modifications in the new 5-speed transmission and handling, viz.: –
- Closer gear ratios.
- 3 map ECU – Standard, Aggressive, and Smooth.
- Centrally placed Shock.
- 49mm Showa A-kit Fork.
- Dunlop Geomax MX3S tires.
With these specs and the overall weight down to 243 lbs, this all new 2017 Honda CRF450R looks to be just what it wanted to be – a top-of-the-line dirt bike.
Pricing and Added Specs:
Honda has announced an optional electric starter kit, excluding the battery, available for $650. What has eluded many buyers is the absence of a battery within the kit itself. There are numerous buyers who would have preferred a complete package and although there is not the official response from the manufacturers, rumors suggest that there just might be one.
Other than that, pricing will be just a tad more than before starting from – $8,849.
Just released, there’s little that this bike seems to be doing wrong, on paper at least. All that remains to be seen is how this 2017 Honda CRF450R performs on the track.
