04' trx450


Im looking at buyn an 04' TRX450 and just wondering if that particular year had any specific problems I should be on the lookout for.

Any advice would be appreciated

The 04/05 engine is different from the later years. Honda overbuilt this engine, and a lot of desert race teams will not run later models. It has a slightly longer stroke, so it has a little more low end. It also has an oil cooler, which later models do not have.

I have no complaints about the frame, except that the quad is a little to narrow. I solved this with a set of ITP Baja rims and Holeshot XC tires, which saves the expense of getting aftermarket a-arms, an axle, and new suspension. The rims are wider and have a greater of offset than stock, and the tires are wider as well, so I end up +3-4" wider, for a nice increase in stability. One must take the time to properly adjust the stock suspension!

If you are catching real big air, you may have an issue with the frame tubes right below the fuel tank. That seems to be the weak spot on the earlier TRX's.

there were alot of problems with the 04's. It was the first year and they had cooling problems, electrical and ignition issues at times. Not to mention that frame issue under the tank. Look for an 05 if you can find one the price shouldnt be much different.

I have two 04's. One that we bought brand new and got reamed for on Valentines day of 04'. This bike has been ridden HARD with many many hours on it and we have not had one single problem with it. It still runs good! That's pretty good if you ask me. We liked it so much that we bought another one last year and rode it all season with no problems. The only major problems that I have heard of with 04/05's is that the cam bearing has failed several people. Like I said, we have yet to have a problem... but the one that we bought new is probably due for a top end.

My 450r that we bought used has long travel suspension with those new Fox Evol Floats. Let me tell you, it is a smooooooooooth ride!

04 and 05 models are just fine if you do good maintance on the quad, mainly engine oil changes. The crank bearings mainly the right crank bearing will go bad if the crank is walking back and forth in the cases under hard acceleration.

      This replaces the tube that connects the two carbs on a 1987 Honda XR600R (it may fit other years). 
      Made in the USA. 
      Constructed of TPU  (solvent safe plastic.)
       Its durable stiff abrasion resistant yet flexible enough you never have to worry about breaking it when you're taking apart your carbs. 
      Fits the o-ring perfectly and slips into the carb nice and tight.
      Matches the rear shock coil. 
      If you would like to buy one contact me via e-mail. They cost $40 Shipping is free (anywhere in the USA). $10 off for active duty or retired military.

      Jeremy Martin Leads the Charge for Wiseco Riders at Daytona Supercross
      Christian Craig Turns in Career Best in 450 Competition
      MENTOR, Ohio (March 13, 2018) – Jeremy Martin showed the way for Wiseco-sponsored riders in Saturday night’s Monster Energy Daytona Supercross presented by Honda. In a season marred by bad luck and misfortune, Martin put together a near flawless ride to earn his first Eastern Regional 250SX Class podium finish of the season.
      Martin qualified eighth for the division’s annual visit to the World Center of Racing, finished fourth in his heat race, and came home second in the 250SX main event, missing his first win of the year by less than a second.

      “It’s Daytona, a real man’s track.” said Martin who sits fourth in points. “It was the toughest race of the year as far as fitness. I had to slow down a little bit, halfway through the main. I was getting close to (race winner) Jordon (Smith) and I was starting to think about where I could make a move on him, then I made some mistakes and he got away from me. Couldn’t quite get close again, but it’s good. We’re on the podium and in contention for wins again. That’s something I haven’t been able to say in supercross in a while. We want to get wins and now we know it’s coming.”
      Martin’s podium was a bright spot, but the rest of the event was rough for the GEICO Honda/Factory Connection squad. RJ Hampshire crashed hard in his heat race and had to be transported to a local hospital. He injured his back and ribs, but shoulder pain left him with the most concern.
      “I felt good on the bike all day,” said Hampshire via his Instagram account. “Had some pretty good speed and my foot just slid off hitting my shifter in those rollers during that heat race. After seeing the pictures from the crash I’m very thankful I didn’t take a shot to my head. I have some fractures in my T3/T4 in my back and ribs. Also have some damage to my lungs which is why I’ll be spending a couple nights in the hospital. I’ll be getting some more checkups this week on the shoulder also.”
      Cameron McAdoo, the third member of the team, was unable to compete at Daytona after being sidelined with a hand injury two races ago in Atlanta.
      Across the paddock, in the premier 450SX Class, Christian Craig got the call to fill in for Team Honda HRC. With the team’s regular riders Ken Roczen and Cole Seely out with injuries, it was up to Craig to carry the load for the factory team, and the upstart rider didn’t disappoint.
      The San Diego native was solid in both qualifying sessions, won his heat race and snagged the holeshot in the division’s main event. After relinquishing the lead to eventual winner Justin Brayton, Craig continued to show he was up for the challenge. The 26-year-old rider raced for second and third for most of the 20-minute-plus-one-lap feature before losing one more spot in the late goings to bring his No. 32 Honda CRF450R home fourth in the final rundown.

      “I had a great week testing with the team,” commented Craig. “They came down to Florida right after Atlanta and I feel like we really improved. Just getting more time on the bike and getting more comfortable was huge. I started off race day feeling really good. My qualifying position didn’t really show it, but overall I was happy with my riding. It’s all about having fun out there, and man, that’s what I did tonight. I was up front in the heat race, fell to third, but then the two guys in front took each other out so I ended up winning. You can call it luck or whatever, but I just put myself in a good position to capitalize on people’s mistakes."
      “I had a good gate pick and some confidence going into the main. I grabbed the holeshot and led for almost the first lap, but [Justin] Brayton got by me pretty quick. I stayed second for quite a while. I just rode my hardest and did my best. Unfortunately, a couple guys got by me so I ended up fourth. The track was so tough. This is only my second time racing Daytona and last year didn’t go well, so I really wanted to get some revenge this year. It’s better than the week before, but man, I was so close to a podium. I just need to keep putting myself in good positions and work on getting better each weekend.”
