GT250R tries to kill me

[vtec]

Bloody hell, this thread has turned into a softcocks wet dream, everyone bitching about him doing 160 on the open road? If you haven't done 160 in your life then you are a bloody saint.

The guy's brakes failed on a relatively new bike, and you are all somehow twisting it into the riders fault. The front brake lever flaw is extremely dangerous at any speed. Could be enough to send you out in front of a car at 60kph.

Also, saying that a bike isn't designed to handle braking from 160kph is just plain foolish. I've ridden stacks of bikes and the only bikes which I've had braking issues on were a Hayabusa on the track, cause it got fade from braking from 260k/hr, and my CBR600 race bike, had warped discs so uneven braking. My CBR250's have never had any braking problems (except from when I got some air bubbles in the lines which was my fault), and thats been braking from 190k/hr down to about 60 from the 100metre marker on Pukekohe, and similar situations on Taupo and Manfeild. If the Hyosungs brakes weren't designed to consistently stop it from 160kph I would throw it in the rubbish right now.

R6kid, can't believe you got into the lecturing aswell, I've ridden with you at 180 when you had a pillion on your R6 and I was on my CBR250RR on the way back from Paeroa a few years ago :P

i think a few too many ppl on here spend too much time on there ass typing and not enough riding....

Not to mention the naked hypocrasy of some.

[woza]

there are many ol hobags out there have done many km without this happening... so who knows the whole story behind why his brakes failed in the first place.

Um, he does.
You failed reading comprehension, didnt you.

It's something i'd certainly be checking if I owned one. Although if I didn't use that lever setting it may not be an issue. But for those that do...

lol, look at the post count respectivly with those who are bitching ^^

[woza]

i had it set to 6 (the furtherest it goes out from the bars) with some testing we found that when its on 6 and you pull hard on the brakes it clicks over to one and the leaver comes in against the bar and its not far enough in to bring on the brakes......

Thanks for the post tho, i will definely make a point of checking my brake position. It seems this thread has just turned into a bit of shit fight, but oh well good that you posted up about it anyway.

[Mr. Rock]

I don't get it. How come the bike gets the blame after being abused and misused by an idiot rider?

that is very true.. i wood agree.. i have had no issues like that.. and its a 250 what do you expect, if i didnt have to buy a 250 by law i wood never get a hyobag. but since i do have to get one i think its a good chunk of bike for the money and doesnt look as small and pathetic as other 250 with there pizza cutter wheels etc.

dude, stop making sense, no one can be trusted to ride as fast as me!

I'm sure you didn't mean it that way but I read your post as bragging about how fast you were going and that the brake failure was a secondary point.

If you don't want people to give you shit about something don't put it out there in KB land eh

[Donut]

lol braging and a hyosung.... oh and speed now theres a joke

[_STAIN_]

turns out the rear brakes had seized and the front brake leavers adjuster is faulty. i had it set to 6 (the furtherest it goes out from the bars) with some testing we found that when its on 6 and you pull hard on the brakes it clicks over to one and the leaver comes in against the bar and its not far enough in to bring on the brakes...... one more for the book of shitty hyo-bags i think...... now i just cant trust the bike and dont wanna go over 50 and wheres the fun in that

There is a problem out there with rear brake mastercylinder seizing that owners should be aware of. I have replaced a GT250 one and have had a dealer request one recently. Currently wrecking GT650 which had seized it's rear mastercylinder.....maybe contributing to accident...suspicious. Would strongly recommend brake fluid change as collecting moisture in brake fluid could be contributing to them seizing.

Good ole KB, missing the point again. Nice to be all high and mighty.

What has happened here is a serious safety concern and has nothing to do with the speed he was travelling. Are you saying that if he slammed the brakes on from 100km/h on the open road to avoid an accident and this happened that it would have been ok?

For fucks sake people. This is a serious bike fault and i'd be concerned if I was riding one about whether I could trust the brakes or not.

With you 110%.

What also concerns me that some members who are supposed to be providing guidance don't appear to have recognised the real issue here. Instead of taking the easy and incorrect option of reclassifying an obvious serious mechanical malfunction as "idiot rider" and walking away, they should be informing their local GT250 learner members of a potential problem with their bikes, flagging this thread to them, and helping them to get their brakes checked out before they ride again.

Well... are you?

The master cylinders seized? Not the calliper?

So are master cylinders different to callipers then in that respect -- all of a sudden seizing up with no warning in the middle of the ride, unlike callipers which slowly seize up from moisture and corrosion etc.?

Or was this perhaps a case of somebody neglecting maintenance (not preventative maintenance necessarily, but by ignoring a fairly major malfunction) and riding a bike that they knew had seized brakes?

the bike has been well maintained and is cleaned and checked once a week, this is not the first time my hyo-shit's brakes have failed me.... the first was when my front calliper fell off, this time the master cylinder seized...... nothing like cheap shit... back brakes not the biggie was the front i was more worried about, the only time you need back brakes is for wheel stands and i wont be doing any of them on the hyo
