Most of the '19's do. Think it's just the Suzuki which doesn't now but could be wrong...

EDIT:
Sorry, just saw you talking abouit 250's. Don't think the Kawi 250 gets elc. start - maybe in '20.

 

I'm not convinced that I need the button. Got to admit that I don't do really technical stuff though. Motocross and HH/playdays and racing with CEC.
I've got a core exp 3.0 in my 17 rmz250 and the engine never needs to be restarted. It's cut out/stalled twice since I fitted it in May (or whenever it was). I wouldn't change that bike for anything, it's so good (at my level anyway). All I've done is ride it since last August and changed the tyres a few times. I haven't even tried the other 2 map settings.
I'd probably look at the Honda if I was going to get a new one though. They've got the button.

I'd go for the Yamaha. One of the best engines (prob best enduro / H+H motor), IMO best build quality, by far the best suspension, elec. start. Shame it doesn't have Hydro clutch although with a nice Pro Taper / WC perch & lever they feel pretty buttery!

I'd personally steer clear of the latest gen. Honda. Not ridden one myself but the engine it apparently pretty flat and likes / needs to be rev'd to get anything out of it.

 

Yes, the Yam 250f has won the ama outdoor 4 out of the last 5 years. Aarron Plessinger just took the title on it. It's agreed that it's the best bike by the experts.

They said that about my bike though, it was the least powerful of the bunch (38HP), but at my level it's more than enough. Good bottom and mid with the best cornering chassis, that's why it makes such a good play/all round bike.

Didn't Al Ranger post something recently about the Honda? It won a HH race straight out of the box with just clicker adjustments. I'm sure they said it was a really good bike.

 

Snowy Won day two of Rhayder BEC last weekend, which was brutal ( a couple of very handy Experts were treated for Hypothermia ! Yes Wales in August ) on a Honda Cr 250f, the bike is almost stock apart from Yoshi Pipe , he does have some Full Factory WP suspension as KTM keen to get a set on a None KTM / Husky supported rider.

Does the 19 inch rear wheel make any difference to grip for the easy enduro stuff? I don't bother with any of the extreme trials stuff, just the odd tree,pipe,tyre obstacle.

 

It doesn't make any difference to me. I've been using starcross 5 soft and mediums on the front and rear for 4 Cotswold races so far and my only problem was the soft front on a hard track. The rear seems to work well everywhere.
I was going to get an 18" rear rim and build an enduro wheel, but I really don't think I need it. I thought I was on the best bike at our last race at Long Compton, definitely no disadvantage to an exc. I used less than 4 litres of fuel over 2 hours and got 2nd in the wobblers class. We do a mix of mx practice and HH racing/playdays and it's a perfect crossover bike. Honestly just a few clicks on the compression settings front and rear and it works well everywhere at my level.

 

My rear is only 100 wide but I really don't want a bigger heavier tyre on the bike. The first shuckborough race loads of people were getting stuck on a big cambered climb in the forest but I didn't have problems with that starcross 5 soft. Migh be an issue if you need lower pressures or ride in rocky terrain, but the stuff we seem to do they're absolutely fine and probably more stable at speed in corners.

 

Recently fitted a Rekluse, other that I honestly haven't had to touch a thing since getting it new 12 months ago. Starts first or second kick every time. I think it's a really good all rounder. It makes my 2015 350 exc-f feel like a bus.

 

Sweet i ll keep an eye out for a MX bike then as I don't use my exc at all on the road and now with the stiffer suspension it handles like shite.

 

I know someone who bought a new 350 sx-f and he's finding it to be a bit of a handful in the same conditions where mine seems fine. So be careful what you go for. I think the extra power is just a liability unless you're prepared to use it.

 

I swapped my 250 crf for a newer 350 exc f ,and found it not as nimble on the corners.its coaught me out a few times when green laning ,last time I went wide on a trail into rough for no reason straight over the handle bars!but the extra power is much better for getting up things.and not as taxing after 6-7 hours in the saddle. So swings and roundabouts I think!

 

Yeah I know all about that. I had a couple 250 2t MX bikes then a 125 then 450 and now a 250f and couldn't be happier with the lower power. As my mate said "why make a hard sport even harder?"

 

I wouldn't say that they have bad handling. It just feels big compared to my rmz.
Obvious thing to look at would be your suspension. Make sure the sag is correct, if you're too heavy for the rear spring the bike will chopper out. Put one foot on the footrest standing at the side of the bike and compress your suspension, check to see that the front and rear is balanced.
The 350 is a great bike, I'm just not big enough to use it properly on a track.
