It's pretty obvious that you have not ridden an Alta. I know people who had the same opinion as you, but then they rode mine! I was skeptical at first, then I saw Hill on one at straight rhythm, test rode one, and got a tattoo.

lecoen Added a reply to RM250 '10 Transmission tear down, assistance needed with parts
10/19/2020 11:46am I change the oil every 6 hours. Just going to replace the whole lot. Adding in extra shims is also something I was thinking about as cases might be a bit worn. But on the other hand I read and hear that it's quite common for these transmissions to let go after the amount of hours I put on it...

10/29/2019 6:51pm So my crankshaft rod seized up today. I am trying to understand why it happened and what can cause this. Just some info so maybe someone has a tip for the future. -bought the bike 4 years ago and have put 70hrs on it. Piston was changed 35hrs ago. But I don't ride that hard. -Mix ratio is 40:1. I...

10/29/2019 1:58am Thanks for the replies. Seems it just was long overdue to change the crankshaft, lesson for the future. So brought it to the shop to change crankshaft, replate the cylinder and new piston. I am just a bit surprised by the number of sand marks because I do change my filter every ride and buy new filters every year. I...

2/2/2017 7:48am Sorry to bump this up. The rear brake on my RM 250 08 is jacked up. Anyone know if something other then OEM fits on it. Cannot find a used one anywhere.
lecoen Started a new thread hole underside crankcase RM250 '10
4/13/2016 7:37am It's me again, after welding the frame I am checking the underside of my bike for cracks a lot and I noticed a small hole in de crankcase: 
Nothing is leaking out of there, I am wondering if it can do damage and if I should fix it. Thanks!

4/13/2016 1:56am The hole is along the split line of the cases, so not the inner clutch cover. I'll make some better pictures and post them.

3/27/2016 12:13pm So at the track today I noticed 3 cracks in my frame. 2 at the engine mount and 1 at the subframe mount. All the cracks are on the left side. The previous owner powder coated the frame so I am wondering if this has something to do with it. Do you guys suggest to stop ridding immediately or is...

3/25/2016 5:42am Does anybody know what are the differences in the frame of '01 and from '04 and up?
lecoen Added a reply to RM 250 '10 cracked frame
3/21/2016 8:13am I hope you are correct. It seem to be my only option as there are no frames to be found anywhere on this side of the pond of 2004 and up. Of course there is always the possibility of buying from Suzuki for more then a grand. Unfortunately this is not an option for me.

3/21/2016 3:21am I weight 72kg and I am for sure not hucking huge jumps to flat. So that leaves the loose engine mount bolts. As for puting the engine and swingarm in. The welder wants the bare frame. If I cut some aluminum pipes to the exact length of the engine width where the mounting bolts are, same for the swingarm and...

3/20/2016 11:36pm So can we assume the reason why it cracked is because of loose engine mount bols? Do you have other suggestions why it could have happend?

3/20/2016 11:21pm Been doing that, until now I cannot find any. I'll keep looking and get it TIG weld in the meantime.

3/20/2016 11:16pm I checked the engine thoroughly, fortunately I didn't find any cracks.

3/20/2016 12:09pm After I bought it, about 2 hours in, the gearbox was completely trashed and all gears, the clutch basket and pressure plate have been replaced. When I pulled the engine out for these repairs I noticed the engine mount bolts where loose. So as you say this has probably been the source of the cracks. I hope after this is...

3/20/2016 9:20am Buying this is also an option: http://www.ebay.co.uk/itm/SUZUKI-RM250-MAIN-FRAME-CHASSIS-RM-250-01-/28… Update: Never mind, Only frames from 2004 and above will fit.

3/20/2016 7:42am It's worse then I thought. Both engine mounts on the left side have 2 cracks. So that comes up to 5 cracks total. The upper engine mount is loose because of it. And the one above the subframe mount is pretty deep too. Both engine mounts have cracks: 
Upper engine mount: 
Lower engine mount: 
Crack above...
Upper engine mount: Lower engine mount: Crack above...
