gt125r to gs500 update and pics
« on: June 30, 2010, 07:27:46 PM »

Well you no when you start with a good idea and it turns into being a nitemare! well this is one of them ideas.allthe lugs and mounts have had to be moved and the frame front piece (the fixed one) has had to be lengthed to accomodate the crank case not by much mind.
the engines sat in the bike and should all being well be mounted in by end of play today,if your are thinking of a conversion like this be warned,its not easy!

A good bit of advice change the forks to some stronger ones since the 125 ones are very weak a bit of harder braking will bend them and with 500cc engine more weight ect they are even weaker

????????????

Looking at the Parts Book for the GT125/250R use the same part number, so where do you get the information that the 250 forks are "stronger" also note that the early gt650 used the same fork as well.?

Im gonna sell the 250 project bike we've been working on for the last year,  but before we rebuilt the engine a few weeks ago we were gonna attempt the samething too, the connection between Hyosung and Suzuki is to tempting not to attempt this converstion if you ride a bigger bike and your 125's got a stuffed engine. For some of us old enough to remember, its a kin to stuffing the Rover/Chevy V8 block in a Triumph Stag best of luck with this mate im really keen to see the finished bike too.

Let me know if you need a hugger.

Fantastic, what a great little bike, a better machine than the original hyosung donor bike and a much better looking machine than the GS500.

I reckon there's a business right there, now rebrand it as your own..!

Get an aftermarket bandit rear shock and a motard exhaust and your all sorted...!

Lets see more pic's again soon.

Never said they were different i only said the fork hyo produce are piece of shit and i could bend them with my arms and knee trust when they were bent and i straightened them on the press they took 1 ton to unbend now that's jokes they are definitely not safe for 500cc engine or hard braking. You might not want to believe it but its simple true just trying to help. I dont know about the upside down ones since i just noticed you have those maye they are stronger

Fair point, the standard telescopics on our early uk 125 comets are skinny horrid things, my 250 has gold anodised upside down versions as shod on 650's and later on GT125R's.

Complete showa rip offs and brillant when the oil has been replaced with decent stuff and I belief 400cc's per fork leg.

IMHO one of the bikes best features.
