Hi peeps not mine but wanted to share.

"was hit side on by a 307 pulling out of a turning right in front of me, was only do 30 as well, luckily only damage is to the bike apart from a couple of bruises and small scapes"

how much force is needed to snap the yoke on a bike? rider says he was only do 30 but can the metal be this weak?

I'd expect the bike to be mashed to bits for it to snap like that :o

yeah all it did was snap the yoke and rip the left hand grip/switches off, couple of fairing cracks but not much else, i'll share more pics if he send them

I take it most of the damage was from the car rather than hitting the floor?

yeah the force of him hitting the side of it, still think he was lucky

yeah I bet, surprised he didn't get his hand trapped. lucky it was by a turning so the car wouldn't have been at full speed

It's not just a case of the rider doing 30. You have to think of what speed the car was doing, then the two combined speeds colliding and the energy realesed as they both decelerate to 0 mph, quite a lot of energy being released

yeah i figure SG but you'd think most people would crawl out of a blind turn....

That head brace is only made of cast alloy of debatable quality. Looking at the photo it looks pretty thin below as well. Look at the break line to see how much porosity is in it.

How it was hit is also a facture on how it broke - odd angle to best strength.

Its better it broke now than be riding with stress cracks in it waiting to fail when you are doing a ton somewhere.

I bet that is not easy to replace either - I would be very surprised if that was a stock part. A good welder could fix it and the weld would be stronger than the original part was.

it's a Korean bike!!! Thats the gamble you pay buying them. It's not worth fixing!!!
If it were a recognized manufacturer like honda, yamaha etc it would be worth fixing IF the frame were ok. Learn from it, lucky escape.

He'd better strip it down and see what else is damaged; lower yoke, forks, headstock. I'd be surprised if the damage is limited to the top yoke alone... :-?

Those are stock on the Hyo, you saying its poor quality?

Cheers scotty, i'll pass it on.

Hey Newnut, ever ridden a suzuki before? Ever ridden a hyo before???? More features on mine as standard then you get with some of the other jap makes on a 250

seems hell lot of damage for such a "low speed" impact.

i rammed a dt125r into a brick wall full belt (not on purpose no lol)

all i did was buckle the front wheel

id be reluctant to fix because of underlying unforeseen damage

I hadn't made it to 30 when I took a hit from the side this year, did bust up a fair bit round the front of the bike

I think at some point me and the bike were up on the front wheel alone as the back wheel ended up on the car bonnet.

The bent in rim on the front wheel is odd I guess it got pinned on something solid on the car.

guess it all depends on the impact energy angle of impact etc each crash and each bike will have differnet outcomes

Very true but the speed of the car is unknown. So far this looks like only damage and everything else is ok but won't know for sure till garage has inspected fully
