presentation of the CRF 450 R 2011
the CRF 450 R is a must-have for riders looking for the best machine to take them to victory. Powered by a 4-stroke engine with Unicam timing system that delivers full power at the slightest twist of the throttle, the CRF 450 R still benefits from an aluminum frame and suspension derived from official machines.aluminum frame and suspensions derived from those used on official machines, now with the addition of the new HPSD progressive steering damper system.
pERFORMANCE
the CRF 450 is powered by a 4-stroke, 4-valve Unicam engine delivering 56 hp at 8,500 rpm and 5.15 mkg of torque at 7,000 rpm. Since 2009, it has benefited from a new fuel injection system with automatic adjustment, guaranteeing identical character and performance at all altitudes.
tECHNOLOGY
available as an option, the programming kit developed over many years by HRC is extremely easy to use, providing precise data for optimizing the machine in every situation. Ignition timing and injection programming can be modified by connecting the machine to a computer and simply following the instructions provided. The system radically simplifies tuning procedures and allows the greatest number of people to personalize their settings. The machine is connected via a single connector, with no need to remove the fuel tank.
sAFETY
lightweight, compact Honda HPSD progressive steering damper system, developed by Honda to improve cornering efficiency and reduce rider fatigue.

Bikers' reviews Leave a review - 9 reviews
Especially with the 2027 model, which has come a long way: more torque, more power, and a lighter weight. The Honda CRF450R is, in my opinion, by far the top bike this year. It’s an even more efficient and enjoyable bike to ride, setting the bar very high for the competition. Rating : 5/5 Respond to Raphael
I chose the brand and displacement of a 4-stroke because it was low-maintenance (slower engine with oil bath lubrication), but less powerful than a 2-stroke with the same displacement, hence the 450 displacement. To tell the truth, a 250 CR 2-stroke would have been more than enough, and it also met my needs in terms of power, but not in terms of maintenance, noise, etc...
The KTM, the other queen of the field, was also on my mind, but having bad memories of the Swedish brand, I didn't want to fall back into the horrors of the past, and even though I know that they've made a lot of progress since then, particularly in terms of reliability, and that today their bikes are up to scratch, I preferred the Honda. So a Honda 4-stroke powerful enough to have fun, what choice did I have?
The 350 CRF L and the 450 CRF.
So I chose the 450 CRF, and I don't regret it.
Pleasant and versatile, smooth and brutal at the same time, powerful but not too powerful, inexpensive to maintain, in short, it's a joy to ride, as those with a vocabulary would say... One criticism, however, but valid for all the bikes in the line-up, is the height of the seat...
Which wouldn't be a problem with a starter, but until 2016 they weren't equipped with one, and as I have a 2016 model... However I'm aware that to have a good riding position and good ground clearance, the bike has to be high, but this is problematic when you have to kick...
So despite my 1m80, I do it on the workshop stand or leaning against a wall, otherwise it's a bit difficult, the seat being perched at 95cm... In summary, you can go for it, I don't think this bike will disappoint you. Rating : 5/5 Respond to Christopher
