1/11/2025 8:41am most of the complaining I hear is from older guys and guys that get to bounce from bike to bike. The youger guys on 250 are made of rubber ha

1/11/2025 8:39am thats interesting, so far Ive only gotten a twitch on the new yamaha but not the new honda. My friends 1018 honda however is a handful. Seems to me Honda may have done somthing good in the stability dept on the new bike

1/11/2025 8:37am We know the hype of the 2021 was not justified. Sounds like the hype of the 2025 is on the rocks. Interesting the frame is near identical on the 250 and the complaints far fewer.

1/11/2025 8:36am It is interesting that you notice this on the Yamaha/Kawi. I think most people would say those two brands have had the most comfortable frame feel for years.

1/11/2025 5:42am thanks for that My experiences dealing with structural resonances has me VERY skeptical that suspension mods are the answer to the CRFs frame harshness that so many perceive as a "rigid frame". Its not nearly as rigid a frame as the yamaha and we all know the story on that bike is the opposite. YES the yamahas suspension is superior...

1/11/2025 5:13am To the op.. I felt the same about my 21we. I dont think much has really changed in that feel department since. Bought a 23 yam and after about an hours worth of riding, i got used to the initial different feel. Long story short, both of my bikes i mentioned were stolen. Picked up a 23sr as my first kawi in 29 years of moto. Great for play riding but too lethargic in the handling department even changing clamp offset. Back at 24 yam and i literally love that i feel like i have the best of both worlds...

1/10/2025 9:02am agree that the 350 seems to have better more "throttle response" BUT its a feel more than an actual in that as soon as ya get into any thicker gooy or deeper sand the 350 has to be reved hard to avoid a noise dive where the 450 easily plows through unfazed. Mostly east coast issue. The 350 was enough...

1/10/2025 8:58am I dont believe its as simple as "dont like AL frame". My 2022 sxf has the same harshness in the rear as the 2025 crf450. As well Ive done decades of design and development work with these materials and its all in the exacution, not so much the material. Steel does afford more lattitude in what ya can do because...

1/10/2025 6:52am Perhaps read up on the previous generation 20-24' CRF chassis adjustments. I think Honda tried to address them with the 25' chassis package but your mileage may vary. Bars, triple clamps, chassis bolt torque specs, rear wheel distance, extra sag, etc...all played into making the 20-24' CRF chassis more compliant and comfortable. I have a 23' 450R I've been chasing some of this stuff on and it def makes a difference.

1/10/2025 6:57am Im not sure this question was directed at me, but heres my take on the compare between the 25 sxf350 and the 25 crf450 Ive been on ktms for the last 5 years and they are superior to any jap bike in these areas... Breaks, the brembos really are usefully better. They are more linear and consistent. I didnt realize...

1/9/2025 7:45pm As CBE mentioned springs. At 195# Factory Connection went to .53. kg fork springs & a 5.7 on rear. FC recommended 108 sag, fork 2.5mm showing. last years shorter springs work with a spacer or FC machined a new clip in inner fork tube for lower spring seat. I raised fork oil from the 340ml they sent it back with to 345 may go 350 re valved yes .The base valve is firmer than stock, mid is more progressive. oil up from 313ml .rebound stack is stiffer & more progressive than the stock stacks. Also they drilled a 1mm bleed...

1/9/2025 7:48pm interesting yea I had a 2025 sxf350 for about a month. I didnt like having to rev it so on tacky or sandy tracks so I sold it Also didnt care for the angle of the seat. It was a bit rear high and not a flatter slope. My 2022 sxf 450 and the 2025 yamaha and Honda All have...

1/9/2025 2:16pm yea the older hondas say 2007 had a much flexyer upper shock mount. not sure if the spike was washed there ? It can be a nightmear in some structures to tame a wiggle and keep the performace iit had in all other areas I have talked to FC and Fcp. They wont say straight up that they can eliminate...

1/9/2025 2:04pm With your background you would probably have a better understanding with resonance and transfer of energy but I have noticed the biggest difference between the Honda frames over the years and the Kawi/Yami frames are the relief holes. Kawi and Yamaha both have relief holes drilled in every section of the frame of varying sizes, underside of the swing arm each side, 2 holes where the linkage mounts, inside of the perimeter section each side and so on. The Hondas only have one hole in the cross member where the shock mounts. This is why I believe the Yamaha and...

1/9/2025 2:03pm Stock shock spring is a 5.3kg that is too light for 180lbs. I’m 185lbs and should be a 5.5 or 5.7 rear spring. preload close or over 10mm probably need stiffer spring.

1/9/2025 12:03pm Its true. BUT the Kow has some serious vibration compared to the Honda and the Yamaha that was a deal breaker for me

1/9/2025 12:02pm 180 it does need to be a bit stiffer imo BUT this harshness is obvious at any speed. Its not just when your deeper into stroke
