Advice on sm250 please

[Niall-griffiths]

Hi all recently sold my ec300 to go to a supermoto route I've found a sm250 but have some questions

what is the differnce between the sm and ec apart from wheels and front brake? I guess perhaps the suspention is abit more firm??

How many hours/miles should I be looking at top end rebuilds? These are no problem for me but could I go once a year? Bike would only be ridden in the dry with warm weather and in the uk there ain't to much of it lol.

also can these things take half hour 60mph trips on and off without being under to much stress?looking at specs they seem to have the 6 speed box so if I gear taller I imagin this shouldn't be a problem?

this is the one I'm looking at do you guys think its reasonably priced??

i converted my 300 to sm and have the best of both world.
i would not dare hold it open for 30 mins at 60 unless you really want to play with the sprockets larger front say a 15 and smaller back 45 ish to do that, i use a 13/14 front and i think its 45 rear i cruse around at 50 i even tried the motorway and shat my self when all lorrys over take blowing me around lol. there are good for short sprint around country lanes and are bloody good fun.
i would say the engines are the same, frame too not sure about the suspension valving tho

bike looks nice i recon its worth 1500 there quite rare, if i sold my one i would sm it up and try for about 1600

Managed to get it for ?1200 with a years m.o.t

thanks for reply grant. Does it really struggle at 60mph? The guy reckons it maxes around 90 so I wouldn't of thought it a problem it wouldn't be motorway it would be 60mph on long roads to get places. Main use will be country roads tho.how long till you needed rings and piston on the road grant ??

[gassergrant]

i had 86 out off my one down hill lol it will sprint wright up to top say 90mph but you will have to back off.
1200 seams good mate. best thing to do is mate is get take it out for a burn and you should be able to work out what you can and cant do with piston and ring again i had my piston in for 2 years with over 100hrs im just in the process of putting a new one in now, wait until it starts loosing power or done over the big 100hrs
there good bikes tough as old boots hope you enjoy it mate sm rocks

Cant tell you right now, but ive got some SM wheels on order for a EC300 2007.

Been driving KTM EXC125 on road for a couple of days. No problemo. Its common used where I live, so use it for everyday stuff, but its stressing at the highway.

13 or 14 - 42/44 sprockets. High speed, low rpm, longer wheelies.. haha

What front caliper do you have on the 250SM? Im looking for a 4-6pot front caliper, dont think the standard EC300 are going to hold up.
ideal "high" speed would be around 55-65mph.

Btw, got my wheels. First thought the rear wheel was kinda skinny, 4,25", but well.. thats how it is.

As for pumps, I used a 16mm radial Brembo on my supermono for a while. A nice pumo, although not as adjustable as an ISR. Now its on my son's Ec300 with ISR sixpot.
On my supermono I use a ISR radial pump with the ISR sixpot. As you might imagine, I'm an Acke Rising fan.

On my Duc and my wife's RD350 YPVS we use standard Nissin pumps from R6 etc. Easy to come by, cheap and functionable, but not very "bling". I guess a Nissin pump for single caliper use (1/2" ?) would do nicely, as will a 13mm Brembo.

I think a 4.25 rim with a 140 or 150 tyre will be just right. Rhe Ec300 does not need a wider tyre, and a narrow tyre makes the bike more flickable. My favourite among the "skinny" is the Bridgestone BT 090. I have used them since they appeared on the market.

Yup. Wheels are on the bike, and it looks stunning
Brakes are killer, but the caliper-adapter did not include a hole for the speedo-magnet. Gotta drill out and thread it.

Can you upload some pics stian ?

Sure I can Anything special you want, or just the hole schabang?

Ive got one here. Its in the garage, due to heavy rain and some electrical problems (lights flickering) Ive got a thread here about it, take a look if you could.



Im in need of advice due to speedometer sensor and magnet. Anyone got a tip?
