Fiddy@Norway, I've been absent for a couple of months, so maybe this is too late to help you decide on your machine, but what the hell ...
Rode my MSO-SR a little bit at Lue MX and offroad complex last weekend. See this link
Louee Enduro and Motocross Some guys in NSW will know the place, you'll have to guess what's relevant to you.
BTW, the Lifan 150 engine (with A1 cam and OKO26 carb) was real good as per usual (it's a weapon on tight MX tracks). I went for 15:39 gearing and rode everywhere in 3rd and 4th with some clutch fanning in slow corners.
Now my suspension really surprised me. Being used to riding on ruts and woops and shitty joker jumps where I normally go, so on the hardpacked MX and SX tracks I did not know what to expect from my suspension (or frame). It handled really good and soaked up some short and long landings which were reasonably heavy for a pitbike. I could hit single jumps flat out and not care about the flat landings or getting jarred or bending/breaking things. The forks were unreal. And I'm a little bit fussy - real plush most of the time, but good bottoming resistance and the front felt planted nicely around corners. The rear never bottomed out harshly either, and that's with 74kg me on the 800lbs/in (soft) spring. Real happy about that. The Pirelli MX scorp tyres were in their element and felt great on the hard pack too. Although going off track could get ugly, clearing or overjumping everything on the MX track was not risky. On the SX track I would NOT attempt the 3 medium (40ft?) doubles or the monster tabletop. On the medium (65ft?) tabletop I had a real go once, and only just rode away from it (landed a bit off centre in the loose clay rubble) so I called it quits after that lap!
The frame did not bend (wheelbase still measures the same). I've yet to check the frame for cracks, or remove the rear suspension bolts, but it all felt so smooth when riding that I don't expect any structural problems.
Call me a mini traitor - but for sure my bike would rip with slightly larger wheels like 14+17 instead of 12+14. Not just over bumps but picking jump landing lines would be heaps easier with some more wheel gyro effect. If you are riding shitty trails then larger wheels just has to be better for you in terms of grip, control and comfort.
My suspension is cheap stuff! To quote myself ...
My suspension:
* MSO forks (zocch copies) with orig fluid and metal swarf *fully* flushed out, and 280ml of motorex 7.5wt fluid in each leg. Stock fork springs with minimal preload, and clickers adjusted as required. These forks are *great* for the price!
* Rear 800lb/in softer spring (I am 74kg and get *much* better traction with the softer spring). DNM shock with a real heavy/thick shock fluid and re-gas. The shock still fades (gets erratic) when heated and is hyper sensitive to rebound click adj, but with new thick fluid it is 50 times better than stock.
