This is the time of the year when many of us start thinking about new bikes. A new 450 mx bike always makes a great Christmas present. Many of us pour thru the magazines, Dirt Bike, MXA and Dirt Rider to learn which one best fits us. This year #33 participated in Dirt Bike's 450 test day. Here are his observations about each of the bikes.
#33 Reports
HONDA: The all new Honda CRF 450 was a bike I was looking forward to riding after the redesign and whole new look. It was very easy to get on the Honda and ride it because everything is in the correct place, fit and finish is usually a Honda trait I have come to expect.
The layout is comfortable for me at 5’ 11” and didn’t require any adjustments. Although the Honda technician, Charlie, noticed I have large hands and did adjust the clutch lever out for me since it was adjustable. Everything else fell into place. The bike started very easily and rolled out with a smooth clutch release. Once on the track and up to speed the bike felt low and squatty for some odd reason. I brought it back and Charlie adjusted the rebound on both ends to get rid of that feeling. What a huge difference I immediately felt on the track. The bike now worked and was more comfortable to ride. The brakes were on par with every other bike, well except KTM. The clutch was good without the fade previous years had the reputation for. The bike turns well, feels stable and predictable and inspires confidence as you ride. The motor seems very good without too much hit and pulls well throughout the power band. It is not a fire breather but it is by no means slow. Suspension in the back works very well and the only money needing to be spent there would be to change a spring rate for a rider’s weight if necessary. The forks are very adjustable with the AIR system. I had to go up a couple of pounds to get the bike to ride a bit higher in the stroke. It was an easy fix without having to change springs. The only complaint I could lodge was the spike I felt when the front wheel slapped down on some jumps. I started to wonder if the Air system had more stiction in the seals to keep the forks from leaking down since the Air was an integral part of their action. The Honda turns well has a good layout for most riders and has a wide range of adjustability to work with that should get almost anyone comfortable on the bike.
KTM: The KTM seems to have some serious potential with a couple of changes. It works well, has an awesome hydraulic clutch, brakes that the others have to put after market rotors on to match and a motor that is waiting to be set free! I enjoyed riding the bike because of all those items but felt there was more available if I could change a couple of things. For instance the rear shock spring just wouldn’t work for me at 195 lbs, it felt like the spring was not up to the task of supporting Bubba (me). It gave me the chopper feeling no matter what we tried. The forks were lowered to compensate and it definitely was a step in the right direction but not the cure. I believe I needed the spring for my weight to fully appreciate everything this bike could do.
The motor is just waiting for someone to take off the “quiet” stock muffler and put on a quiet free flowing after market muffler to unleash the beast hiding in there. The stock set up is very strong once it starts to pull and build a few rpm, it is one of the best motors in the bunch. I can feel the restriction off the bottom with the stock muffler, but there is more and I want it! Back to the brakes and clutch. I had to readjust my braking points on the KTM because the stopping power was phenomenal with less effort and more braking being supplied from the stock set up without being touchy or grabby. Just a nice powerful set of stoppers! Every bike should have these brakes. The clutch is light, smooth, releases cleanly and never needs adjusting! What more could you ask for? Not much except for maybe a muffler and a shock spring.
Kawasaki: I was surprised by this bike. I have limited experience with the Kawasaki and had no expectations, except hearsay of a powerful motor. The hearsay turned out to be true since this bike has a superb motor with a simple plug and play module that raises or lowers the output to the riders’ preference. I rode with the stock module and was impressed with the power, both output and delivery. Then tried it with the higher output module and liked it even better. My logic is that if I can drive a small V-8 or a big block V-8 which would I choose. I liked having the power on tap when I wanted it since it only was going to go as fast as I twisted the throttle. The brakes worked very well and didn’t require any extra effort to haul that big motor down to a reasonable speed. The clutch kept it all under control with good pull and feel. The bike turned very well and yet was still stable at warp speeds. The forks were right in the hunt with the best forks of the bunch and I really didn’t have to do much in the way of adjusting to be happy with the way they worked. Impressive since I am a fork snob and that is the first thing I will snivel about on a bike. The shock was equally impressive and didn’t require any real adjusting except to make the ride height correct for Bubba. It performed better than I expected at soaking up everything I could give it. It was an easy bike to get on and ride for my height and weight. The spring rates, the control layout and the seat, bar and foot peg relationship were all comfortable. Like I said, I was surprised by this bike.
Suzuki: Right off the bat I have to give the best turning award to the Suzuki. This thing turns inside whenever you decide it is time to go inside of someone. The layout of the Suzuki didn’t seem to make me feel cramped which is something I had felt in years past whenever riding yellow. It seemed the Suzuki used to fit someone more Ricky Carmichael size. That was a nice surprise, it fit and was comfortable without the cramped feeling I remember. All the controls function perfectly and without any extra effort required. All very clean and precise feeling. The shock worked well but felt a bit under sprung for my weight. The forks felt the same, under sprung but they still worked very well given the spring limitations. I guess I should go on a diet since that seems to be my catch phrase “under sprung”. But let’s move on to the motor. This thing rips! I did not expect to have this motor rival the others for top honors in power output and delivery. The thing pulls from the bottom to the top and with authority. I was in shock and had to take a second look down while riding to be sure I was on the yellow bike. It made riding the bike a ton of fun since you could choose any line, any gear or make a mistake and still pull without having to clutch it back up to speed. Impressive. As I walked away from the Suzuki I thought to myself no wonder Mike Alessi gets so many holeshots.
Yamaha: Yamaha has the distinct advantage of being recognizable by the motor and exhaust layout. The fuel injection in front and under the gas tank creates a sound as you open the throttle that none of the other bikes possess. You hear the air being pulled into the air box. It is strange at first but disappears as you ride the bike and get used to the sound. The motor has an almost infinitely adjustable motor if you have the GYTR programmer. You can make the motor hit hard or smooth out if you enter the correct numbers, it is all up to you. As far as the stock motor goes it runs well, starts easily and is by no means slow. It is not the horsepower king but doesn’t have the grunt down low that the Suzuki and Kawasaki have. The backwards motor for some strange reason seems to have more compression braking than some of the others, I have no idea why. I just noticed that when I closed the throttle it seemed to load the front tire slightly more than the other bikes. That didn’t hinder the turning prowess since it turns as well as anything, except the Suzuki which is in a class all by itself. The layout of the bike and controls are a good comfortable layout that feels right. Nothing out of place. The brakes are good and progressive with good lever feel. The clutch seems to take a lot of abuse without a whimper which is good since the bottom of the power band could be stronger. You will use the clutch to get things back up to speed more often than the others. The forks work well and can be dialed in to suit a rider without too much trouble. The shock was impressive. The rear end of the bike seemed to take everything I could dish out and made me want to wheelie through anything rough because it worked so well. I had fun riding this bike but would like to see more from the motor on the bottom.
If I had to pick the one I would want to ride as my own I would choose the KX 450 F. After that it comes down to what color matches your riding gear because if you aren’t winning it isn’t the bike.
