2018 Honda TRX450r Specs He’s coming. But he’s not here yet. We’ve been hearing the rumors, watching the market and listening to tracks, and it looks like the new Honda Sport 450 is right around the corner, but probably will be called a model 2018. We hope it will be much more than a fuel injection version of the current 450R. The new Honda will have a completely new engine and chassis. It will be easier and faster than the current version, and it will probably be even more reliable.
First we started hearing stories about TRX450 EFI back at 2009. That was when Honda launched its new generation of two-wheel 450cc Motocrosser. At the same time, the word of our spies in Japan was that the company was well in its reliability test phase of the quadruple version, which is the last step before production in the fairly elaborate development process of Honda.
But market forces intervened. The existing 2009 TRX450R took a point-blank double-barrel shot at the showroom floor, and has been continuously improving over the years. First of all, the housing market collapsed and took up most of the purchasing power of mid-American ATV customers. With the reduction of equity in the home and without lenders to provide financing, the sales of all the sports quads had a great success. Then Yamaha beat Honda to the punch with his phenomenal YFZ450R, and he took the few shoppers he had. The conclusion was that there was an oversupply of 2009 slings in the warehouse, and corporate managers wanted to see those numbers decline before they introduced a new machine. This raises the question, why are we still waiting? Its 2015 and the new Honda that we hope has not yet come out.
Honda’s warehouse is now empty, and dealers are finally asking for something new. But the fat in charge still do not think that the economy has recovered enough to support the cost of the tools of a new sport ATV. Therefore, there will be a 16 TRX450R, but it will be almost identical to version 2014. The EFI 450 will have to wait just a little longer.
When it arrives, the new ATV will have an engine that is very similar to the two-wheel CRF450R. He will be the last generation Unicam design, which reportedly has advantages of emerged from the top-cam engine without the weight of two cameras. It does so by placing the cam directly on the intake valves, which are larger and heavier than the exhaust valves, and using a tilt arm to operate the two exhaust valves. This design allows for greater revolutions due to the reduced weight of the transmission of not having a tilting arm of entry. That design was used in the older TRX450R engine, too, but all in the new engine will be designed to keep the weight to a minimum. The rod and cylinder will be shorter, and the Rev ceiling will be about 11,500.
There’s a big advantage in the delay. The two-wheel version of the 450 EFI has been out for seven years, and Honda’s engineers have an abundance of regeneration from that market. For example, the four-spring clutch turned out to be a weak point in the CRF motor, so it will be reinforced. On the other hand, the gearbox of the existing TRX450R ATV is the weakest point of that machine; It’s been like this since 2006 when the engine was last changed. At that time, Honda technique of bad roads by electricity with motor-start 450X, and someone had brilliant idea to start issuing in the market the same motor in ATV. It would have been nice, except that the gearbox was not as strong as the original TRX450R. As a result, runners like Joe Byrd continued to base their race quads on the TRX450R 2005. In the hand of the public, 2006 gearbox was adequate, but it is never satisfied with Honda brought adequate. So the new transmission will be stronger.
But the big news, of course, will be the fuel injection system. Honda engineers have two options here: they can use a Keihin system, like the motorcycle, or go to Mikuni. Japanese manufacturers also like to keep two vendors on hand for most components, and the Yamaha YFZ450 uses a Mikuni system with good results.
To the disappointment of those who expect a race-Ready 450, which is not on the cards. The Honda will fulfill the standards EPA, which means that it will be clean and quiet. Motorcycle version avoids these standards are imported as closed competition course of the vehicle. That designation will not work for a Quad, as the research shows that very few of them have run. Yamaha and Kawasaki both have EFI systems that meet government emission standards, and both are performed well in stock adjustment. It is unfortunate that Kawasaki has just stopped production in his 450 sport. The only problem is that if replace muffler and open airbox for higher performance, it would be very injection lean and some EFFI modifications would be necessary. Suzuki tried to get around this “hiding ” a second fuel-injection map within the Quadracer 450R’s electronic brain. When installing the Yoshimura cherry pump, you can access these settings and get the full benefit of an aftermarket pipe. We liked that system, but the government did not, so the Suzuki was withdrawn from the market a while ago.

Suzuki got into trouble by having a system that was too easy to alter, and the 450LT-R was taken out of the market, while things were fixed and didn’t come back. Honda’s fuel injection will probably work very similar to Yamaha and Kawasaki’s. If you want more performance than stock, you will have to modify the measurement with a part of aftermarket, and corporate Honda maintain your distance. The good news is that the aftermarket will react quickly.
As far as the chassis is concerned, Honda has long been a great defender of aluminum as a material. The fact that Yamaha can morning and Kawasaki defeated Honda that feature perhaps has been a source of minor internal affairs. We expect a full aluminum frame, more similar to the one offered in the Kawasaki KFX450. The width of the chassis will remain roughly the same as the current TRX450R. Later, the market could support a wide-track edition, but not now.
