Ok Bro’s, I said I would give an honest opinion on the two machines, well here it is……….. And it’s a LONG read, final opinion is at the bottom, If you’re a Red Rider and you don’t want to hear someone’s bitching about this bike then LEAVE KNOW!!!! Don’t read anything, go get your owner’s manual and read how to change your air filter…………… Know mind you, I have only 3 hours on the CRF, and have not raced it as of yet (tomorrow should be first race, I was supposed to race two weeks ago, but my MOM passed away). Today I prepped the bike for tomorrow’s race (oil change, air cleaning. I regreased the bike while new so I didn’t have to deal with the dirt factor). During my breakin, It took me one hour to feel comfortable on the bike, and then I was able to dial in the sus & fork height. Owners Manual, they barely show you how to wrench on the bike????? They do sell another manual , if you’ll need if you actually work on your bike…………YZ manual, tells you when you should scratch yourself as well as re-build the whole BIKE. Even thought you’ll probably never need it. Honda’s &%$#@!, YZ Major props Change the air filter, &%$#@! was Honda thinking regarding their air filter. I rode & raced bikes for 30 years, this is the WORST air filter removal and re-installation that I’d ever run a crossed. (Past owner of 15 different bikes). You have to be a Rocket Scientist or David Copperfield to install this filter. Line up turn/twist 20 deg. &%$#@!!!!! My change out was ready to install, oiled, greased, inserted into basket, tried to install into air box, grease rubbed off, it felt like it was not line up properly, could not determine if it was lined up. So, I removed it again and played around with it for about ONE HOUR, so I KNOW that it will seat properly. I’ve read numerous reports from professional’s and they state, that this is one of the primary causes regarding CRF value issue. People don’t install the filters properly, which in turn allow dirt to enter into the motor. It is very easy to SCREW this up!!!!!!!! Give me my YZ any DAY!!!!!! Oil Change, engine and tranny. Three different size bolts???????? 8mm plastic engine protector, ok, 10mm engine drain bolt – ok, 12mm tranny drain bolt – &%$#@!, why not a 10mm????????? Drained the engine oil- ok, drained the tranny oil, and all over the frame it leaked, have plenty of rags with ya to clean up…..I changed the oil filter, took off, installed the new filter, (note, Yamaha has exterior oil line to check to see if system is working, no exterior line of the Honda, they mention’s don’t screw up or else……….. so I get ready to install, I check the cover, three oil holes, ok, so I look at the bike, fours oil holes………..ok, which one do I line up, I finally check the cover again, the cover bolt holes are offset 3mm, not enough to see by the naked eye, but enough so I don’t screw up…..ok I’ll give Honda that one, but it does not state in the Manual about that??? Fill the engine oil, ok…….try to fill the tranny oil……….&%$#@!. Should we change the name from CRF to &%$#@!??????? What was Honda thinking on this one?????? Maybe they are in partner with the BillyMan funnel company or what ever it’s called………….. Finish, the CRF looks sweet, but than, ALL brand new bikes sitting in your garage give you that warm and cozy feeling…………..but, no more white creases on the fenders and graphics that bubble after they are applied. Number plates, I installed my numbers & backgrounds from Decal works, they were easier to install than the YZ’s, still same theory tho, windex, warm them up, and use the heat gun or hair dryer……. The plastic number plates are A LOT lighter, which did save them some weight in this category, I don’t know how much abuse they can take and I hope I don’t find out. Rideablilty (I was going wait to post until after my first race. I’ll add a race report in the future) It took a GOOD hour to get used to the feel……….then once it started to feel good, as I got up to speed, the bike felt like my 2002 250F in corners and in the air. This bike loves to jump and have been over jumping everything. I hit a 70’ uphill step up and over jumped it by 20’, flat landed and did not bottom out the susp. The susp is too soft for me (225#) but is still manageable, I’ll re-spring very SOON……… Power wise, it felt a tad under power, only, cause my YZ is geared TALL (15-47). That gearing calmed the YZ for me, but, also allows me to ride most tracks in 2nd & 3rd. On tight tracks I ride the YZ in 2nd……… The CRF had me riding it like a two smoke, I was constantly shifting between2nd-4th. I’m gonna re-gear the CRF, and play with it until I feel happy, but I (being an old 45 geezer) love the YZ’s 4 speed’s………to each his own…….. I love my YZ motor. Suspension, the bike is set up for riders between 170/190, but like I mentioned, it is ride able bone stoke out of the crate. Turn ability, like I said before, this bike feels like my 2002 250F, which means it KICKS AZZ on the track, it corners and jumps PERFECTLY……… CRF hands down Winner. Conclusion. I’m comparing my 2003 YZ450 to my 05 CRF 450. If I could put my YZ motor in the CRF frame, than I’d be in heaven with Mom & Dad. Since I can’t………… Desert riding – YZ over the CRF MX riding & Racing - CRF over the YZ If the 06 YZ 450 comes equipped with the Alm frame, 5#’s lighter and lower center of gravity for better corning, IMO the 06 YZ will beat the 05 CRF 450. If you want a CRF, you’d better prepare to be anal on your Maintenance, the CRF takes twice as long for bike prep than the YZ………… is it worth it, and I’ll tell you tomorrow.
