Taken from YFZCentral.Com
So like I said before, our local dealer got ahold of a prototype DS450. We were able to test it (my brother and I, among a few others). I brought my 06yfz out to compare it to. We were unable to convince them to allow us to take it to our motocross track (and its a good thing too, otherwise we would have gotten hurt...more on that later).
I'm not registered on DS450 central and I wanted to discuss this as it relates to competing with a yfz anyway so that is why it is posted on YFZ Central.
Well, enough background, on to the good stuff.
First off, its not going to destroy the YFZ (yay!).
Here are some things we noticed.
Power: excellent power. In stock trim it has more power than a stock yfz, and it has noticeably more torque. It doesn't seem to rev very high at all. I think the cutoff is 9800 or something like it but I bet it cuts off way earlier than that when we rode it because it seemed like it didn't rev high enough. We didn't get a chance to test out the top end power on it because space was somewhat limited but the bottom end power is excellent. We dragged my yfz (rossier pipe, air box lid off with K&N filter and larger flange, new 18in turf tamers and 15/37 gearing) against it in the grass. It was tough to get the timing down right because it was just my brother and I but we did many drags and it is pretty close in a 200-300ft drag. With a rolling start, the DS loses, but on a regular start, the DS would launch out of the hole and then it wouldn't pull on the yfz. I think it is mainly the tires that provided the separation but there is no doubt in my mind that the DS has an incredible amount of power compared to a stock yfz.
The computer on the handlebars was great, it read tach and speed at the same time and it can be switched to many other things (lap times, fastest speed...ect). Very easy to read and even told you when you were in neutral/gear.
Well, thats about the only good thing on this quad...
It handled like crap.
The suspension was much worse than a stock yfz suspension (my bro made an adequate comment by saying it was just like having 400ex suspension). We didn't have time to tune the suspension but I doubt that it will be able to come close to a yfz suspension even with tuning it.
The riding position was even worse. I felt as if I was sitting right above the front tires as I rode. It is way too tall and makes you sit too far forward. Cornering with it sucked then because of suspension and riding position that we had to really lean off the quads to prevent it from putting so much weight on the outside front tire. Imagine having to ride your YFZ while sitting on the gas tank (with the bars a little further forward than they are). That is what the DS was like. It needs to be lowered a good 2 inches and then something needs to be done to move the rider back as well.
The rear of the quad seems to sit as high if not higher than the front (which causes the rider to sit so far forward when riding). I think if the rear was lowered more then the riding position would change significantly. Also, moving the bars towards the rider would be an improvement.
This quad is NOT ready to go out on a race track. The handling was so bad that we would have for surely crashed on our track.
One thing we noticed was the radiator in front of the frame. Very vulnerable in this position. If you happen to rear-end someone, their rear grab bar is going to smash right into the radiator and you will be screwed. It also sucks in that position because it will get packed with mud/dirt in any kind of racing situation.
Traction was good with those tires and it complimented the power well.
Rear brakes were alright. The front brakes were excellent. We were able to do stoppies in the grass and the front brakes had a great feel to them.
Starting this beast was an absolute pain. I don't know if maybe we were doing something wrong or not but it took forever for it to fire. We started it much like we start our yfz's (with the exception of now being that I have a kicker) and it didn't want to start.
As far as the motocross scene is concerned...don't expect it to start dominating the local circuits. At the very minimum it will need 18in rear tires, and either 50in front/rear or at least lowered seat height by 2 inches, preferably both. Not to mention that the suspension will have to be either redone or new stuff put on.
But, if you do get that stuff, lowered/wider...and then put a pipe on it
, I think it is going to rip.
Our dealer said they were going to be $400 more than the yfz's for MSRP. He also said that ALL the 08 yfz's come with the hi/lo speed shocks like the SE ones had last year??? Is that right?
Well, thats about all I can think of now. Feel free to ask any question about anything I missed.
Oh yeah, here are the pics.
