    RMZ 450 2011 - showa fork problem

    I finaly found the problem! It was the afermarket springs (ohlins 4.4) that i had installed to make it softer when i bought the bike but at that time the fork had other problem with the inner cartridge that was fixed when send them for revalve. But i had left the ohlins 4.4 springs in.... and i figured out that when it was compressed the spring was scratcing at the inside of the tube (the spring has marks on the side) and was stiking because it was softer that the stock or maybe not good spring (although it cost 130€) and i guess it was benting in the tube (i hope you understant what i mean). So now it works free without any friction, but i haven't tested yet at the track to see if the stiffness of the spring is right for me (I am 82kg without gear).... But the diference was noticable from the first moment. Thank you all for your relies and i hope this topic will help anyone that has the same problem. I uploaded some pics to see the springs (at left is the ohlins 4.4 and at right the stock)

    RMZ 450 2011 - showa fork problem

    I opend the forks again and put the tubes on glass rolling it to see if they are bent but they are straight... The only thing that i noticed was when i was reasemble it at the time after i put the spring in the tube and then the inner cartridge i test it to see how it works and it was working very free without any friction, but then when i put the center bolt an the bottom and tighten it, it doesn't work as free and as it was before like it has some friction now... Maybe it doesn't line up with the inner chamber? Or the bushing on the spring seat could cause that? I didn't check that bushing... i though about it after some hours...

    RMZ 450 2011 - showa fork problem

    When i ride it on turns it rebounds very unpredictable and i lose traction, i can't ride as fast as i can because of that... and although i bottom out on some smal jumps (soft on clickers) it beats my arms because it feels harsh on small bumps... it feels like it doesn't get any down like it's locked and i have a lot of headshake on straights.... (don't know how to tell it exactly... sorry for my English... i am from Greece)

    RMZ 450 2011 - showa fork problem

    I just remembered that after my last service on the forks that i changed the bushings and oil, i think it was better but then at my first ride after that i bottomed out on a small jump (overlanding) and i felt it a lot.... so could that bottoming cause some problem to the bushings again? Because i think that after that it got worst ....

    RMZ 450 2011 - showa fork problem

    I bought a used RMZ 450 2011... I have send the forks and shock for revalving and changed the bushings also at 10h and again because it was stuck at 25h... Now the bike has 35h (the hours i have made) and it stuck again after some hours of the new bushings.... I do the procedure of instal the wheel right (I ride mx 8 years now and now to fix it)... But I am worried if something is bent... forks or triple clamp or something else? How can i figure if something is bent? I upload a video on the link bellow so you can see how it stucks now. https://streamable.com/g240e Thank you!!

    RMZ 450 2011 FORK SPRINGS

    I installed the springs from a fork of an CRF 450 2008 that has softer spring (i think). I actually meassure it.... length was the same (495), diameter was the same (43) but wire diametre was 5.2mm on RMZ's and 5.1mm on CRF's so i figure it is lighter.... not knowing the rate for sure. I tested it on the track and i think it was better now... but it still bounces a lot and it is hard... I stiiffened the rebound 4 clicks and stiiffened the comp 2 clicks and became better in handling but i still feel the springing sense on my handlebars. If i go more stiff on rebound then it doesn' work well... i think it packs and feel hitting.... So after that you think i should try the 4.4 fork spring or the 4.6?? (I am between these two) The rear sag i have it on 100mm without riding gear.. *I race and some scramble that are 1,5hour + 2 laps duration... so I will need the bike a little more soft to make all the race without getting so tired by the hiitting of the suspension..

    RMZ 450 2011 FORK SPRINGS

    RMZ 450 2011. I don't know what is the stock fork spring rate... I searched on internet but i found many numbers... other say 5.0 other 4.8 Does anyone knows the stock rate? I am on Europe... Greece (don't know if the USA bikes have other stock springs for some reason??) I am 83kg (182.983678 pounds) and i ride about 8 years enduro, scramble and some motocross races. I had before the RMZ 250 2009 which had great springs for me... and it was very balanced. But now with my RMZ 450 2011 can't get it balanced (the forks are stiffer)... I think i must change to softer fork springs but don't know for sure which rate. Racetech site calculation tells me to put 0.44 kg/mm (says that it has 0.48 kg/mm stock) Is here anyone that is about my weight that has the same bike so he can tell me what to do?? Thank you!!

    RM-Z 450 2011 fork spring

    I have 2 hours on my RMZ 450 2011 that i bought last week but i think the forks are very hard for me... (i am 85kg) I just opened the forks and order some fork oil to change it tomorrow because it was very bad (i don't know how long it was working with the same oil) But my problem is that i can't see the marks on the springs that tell their rate (probably have been erased by working i guess), so i don't know if it is soft, std or hard. Is there any other way to tell what rate are they? Sorry for my english.... i am from Greece!! Thank you...

    Crack where the oil plug goes... Help!

    tig it and never unscrew that bolt again... you can drain the oil by the 12mm bolt on the side (only use a good hexagon 12mm tool because it will be damaged after many drains) that's what i did on mine rmz 250 2009 when i had the same problem.
  15. I own an rmz250 09 and i want to know if i can replace my rear 19' rim, which has a crack, with a 19'' rim from an honda crf250 2013 that one friend has...Does anyone know if ii will fit?
