450SX vs YZ426F?

I'm still on a 426F (great bike, but I REALLY have a soft spot for KTMs) . So, I've heard wonderful things about the new YZ450, Rode a CRF450 ( was great, but soft suspension, made it hard to push it and get comfortable, and I honestly longed for more mid punch), So what I'm looking for is a comparrison between what I'm riding now, and the KTM. The magazines are comparing all the 450's but that doesn't do me very much good. I know it's lighter, and the suspension actually has potential ( or the Works kit is cheep considering... 1,600 USD, and 50mm WP works forks are mounted. Anyone ridden them back to back? Anyone switch from the Blue to the Orange?

As far as what I have learned and heard, if you want more mid range "punch" probably that Yamaha HIT, the KTM won't have that. KTMs seem to have NO hit ANYWHERE, just raw torque and power.

yamahas and hondas make power from 1/2 to full RPMS, KTMs make power from 1/4-3/4. They don't hit though. Raw tractor.

Am I wrong on th 450 though?

Alrighty, here's my opinion on my '00 YZ426 compared to my 450SX. The weight difference is instantly noticeable and the KTM's weight is so low feeling, it's more like a 250 2 stroke to me. The power doesn't hit, but it comes on as soon as you crack the throttle and it doesn't have any tendency to stall like the Yamaha. It's definitely a better bike overall.

I have an '02 YZ426 and love the bike on the track. But it's just too stiff suspension wise, and too tall geared for tight woods. My buddy owns an '03 450EXC. It is much plusher for woods riding (but can still handle jumps), the power is more tractable, and the gearing is perfect. FYI, my YZ is for sale and I looking to pick up a KTM (450 or 525).

I haven't ridden a 426 but I did use to ride a fully tricked rm250 for track and still ride a drz400 for trails. I recently purchased the 450SX and it feels like my rm in terms of lightness, steering, raw off the throttle hit and suspension. But it also has low end torque like my DRZ. The first gear is really tall which is great for mx but means you have to clutch a little in the woods (new sprokets would help). In fact I am waiting to try mine in an actual race. I may actually start in first gear instead of 2nd or 3rd. the powerband makes this thing seem a sleeper. Because it doesn't have a "hit" it has seemed less powerfull than the others but I believe KTM has just managed to put it on the ground in a more controllable way. The throttle responds to exactly what you tell it to do (instantly). No guess work or waiting for the "hit" to arrive. I lined up a couple of times with some other 4's (yz crf etc..) and beat everyone to the first turn. I am not saying the KTM is faster (pro to pro it is probobly even or maybee an edge would go to the CRF) but anyone less than a full pro will be faster on the KTM. Remember a fast bike in the hands of a slow rider is still a slow bike. But if the bike makes the rider better then the combo is guaranteed to go faster.

Summary: balls by exhaust pipe and fighting for controll----yz/crf :)

faster lap times and happy rider---KTM :D

IMHO

      Hi all,
      Well, I’m finally putting my faithful 97 XR400 out to pasture, and have joined the KTM family with a brand new 500 exc.  if Honda would only make a lightweight 400 size dualsport bike, I would....   never mind, that’s a different thread.
      So here I am.  I don’t race, I’m getting old, and this will probably be my last dirt bike I own.  I’d like to keep it for 20 years like I did with my Honda.  I’ll try my best to keep up with the flood of maintenance (what’s the crank rebuild interval for a XR?  40,000 miles?). Anyways, looking for suggestions so I can enjoy this bike into my 70’s.  A skid plate looks to be needed, and some way to tuck the license plate up and still be legal are in my future.  Thoughts?
      Thanks,
      Curt,

      Hey all,
      My name is Jay and i'm new to the forum community but not new to the sport. However I have reached my limit with my expertise and am hoping some of you may be of some help. Without further ado...
        I've stuck to a track most my life, I.E. Motocross, arena cross and outdoor national style tracks. I've made the difficult decision to leave to tracks to the young guns and ride more single track and trail riding up in the mountains. So i started by selling me Factory SLM racing 2012 Yz450F, yes i cried when he drove off with her. But i looked to greener pastures with hopes to have a KTM 500exc, Beta 500rr-s or a Husqvarna FE501. However, almost a year later and I still don't have a shiny new dirt magnet in my shop. I'm in the final deliberations and have narrowed it between KTM and BETA, with me leaning towards the BETA. This is where you come in.
      I would like to know the following.
      Is the Beta service intervals as daunting as the KTM's?
      Is the cost of parts between the two noticeable? And are the just as readily available?
      Those that have a 2017 of either bike, How are they holding up? Can I expect this bike to hold up like a 1985 XR250 (An almost impossible feat)?
      What are any major concerns about either bike?
      and finally what made you choose one or the other?
       
      Thank you for your efforts and advice. I appreciate it.

      I have had this issue happen twice,  my efi and low fuel light are coming on, the bike will idle but soon as you give it gas it will sputter and die. The lights aren't on until you roll the throttle back.  Any ideas? Also the electric start won't work. Have to kick the bike to start,  and the computer doesn't come on when you turn the key and flip the switch to start,. Assuming it's a wiring  issue or fuel pump issue,  any help would be appreciated.

      I noticed my shock spring almost touching my exhaust on 06 525exc.  I pushed on the spring with my hand and the swing arm moved over 1/8"! 
      I know that cant be right but looking at the schematic view of the bearing layout, wth holds the swing arm from moving side to side?  I see the bearings, sleeve, seals and some small cap type things that go on the end of the sleeves  (outer end) but what actually keep the swing arm from sliding side to side inside the bearings?  Looking at mine there appears to be some sort of spacer on the left side between the swing arm and frame beam but on the right, it just looks like the sleeve mates up to the frame?  Am I missing something on one side?  Got this bike in a trade.  So far the motor has been rebuilt at cannon racecraft in OKC, forks rebuilt, and its super clean and runs great other than it needed valve lash set.  So it seems odd that an important part like a swing arm spacer would be mia.  Any ideas?
