Hi team,
As the title suggests, I’m a Hyosung Newby, though I’ve owned more than a dozen bikes before, from small Japanese 2-strokes to several litre-plus sports tourers & adventure bikes.
Today, with a very tight budget at my disposal, I found a 2007 GV650 with a scarcely believable 5,000km on the clock for a bargain price.
The condition of the bike suggests the odometer reading is correct, and it rides very nicely, though as I’ve never ridden one before, I have nothing to compare it to.
The only modification is a ridiculously loud straight-through exhaust, which I will replace with the original (at least to get the bike legally on the road). Otherwise it’s clean & straight.
Why I’m here is that I’d like to call on the collective wisdom of the group to tell me what I should look out for and what problems are moist likely to arise with this model.
Any help will be very gratefully received.
Thanks!

If the bike looks good , generally the GV650 is a solid bike.
Every owner would be wise to:
– upgrade the stator and regulator to a mosfet one (like what you saw on the shop)
– upgrade the caliper pistons to stainless versions and braided brake lines from Goodridge UK.Use motul factory line coolannt.
Look for any burnt plugs near the regulator to see if previous owner put a knock-off aliexpress regulator on it?
Go for a little test ride again and take note of the clutch , if there isn’t any rattle or slips , then the clutch should be OK. They love Motul oils, so as per Hyosung service manual it is advised to use “premium oil” , cheap oils are not worth the engine rebuilds later even if it’s an actual distant cousin of the SV650 (Hyosung made both SV and Hyo650 engines, as they did make engine parts for Suzuki since the 80s before they split up as Hyosung did have an R&D plant in Japan. ) so quality of the bike is dependent on how well the owner looked after it .
Tyres = check for any side wall cracks , then you know if the owner was using OEM tyres or not , at that mileage you said, it likely still has very old rubber tyres on it. So expect to put fresh ones in for a peace of mind, blowouts are not fun.
You also have the comfort of downloading the manuals on this site which will help you look for every small thing during service time.
Lastly , check the forks are in good condition or if they need new seals. If you ever have to change seals, put fork gaiters in to protect them from road pittings as they use GTR forks)

Thanks Macel – that’s just the kind of advice I was hoping for.
The bike is in remarkable condition, cosmetically, at least, and the current owner has only had it for 12 months, so the tyres only date back that far (Bridgestone Battlax – not bad), so I’m hopeful that it’s not a wolf in sheep’s clothing as far as mechanical condition is concerned.
It’s definitely spent its whole life indoors (and barely being ridden, it would seem), so I’ll buy it with my fingers crossed.
Worst case: I should be able to sell that cool-looking but horrendously loud exhaust for about half of what I’m paying for the bike.
I’ll keep you updated and post some pics, if I can work out how to post pics (I tried following the instructions, but the options I’m presented with don’t match what the instructions say – there’s no “add media” button, only “insert/edit media” and when I click that, there’s no option to upload files).

I will login with a test account and post a random picture in this thread to see if that’s the case, and i will fix the bug if i see it. Sorry about this , I was revamping the site entirely , so something might have cracked but i still presented a backup option to upload to IMGUR (website) and just copy their share “BB_CODES” , those BB-CODES will translate to pictures in this forum automatically as it will pull them from a remote source.
Bare with me as i investigate and good luck with your purchase!

OK, let’s try this for a picture. I’ve never used Imgur before but here goes.
While I’m here, I’ve seen that leaks from the fuel tank are not uncommon, and it seems this bike has one – not a big one, but enough to make it unroadworthy.
Can you possibly point me to any info about this problem and potential fixes?

This sucks , IMGUR is blocked in the UK now, so we will no longer recommend it.
https://help.imgur.com/hc/en-us/articles/41592665292443-Imgur-access-in-the-United-KingdomShall we try Flickr (Yahoo’s image host) or even make a folder in your DropBox/OneDrive/Google Drive and call it “Hyo pics” or something, upload a picture there and get the public share link to show here.
Sorry for the run-around, I am also behind on other tasks (was fixing multiple customer bikes & shipping them back) as I had a very long week but I will make sure to look out for your replies.
The site’s own image uploader will be fixed and we no longer will need to use external sites or drive-boxes (hopefully!)

Hi Sven,
I bought a same model which had done just 3.6K. It is running fine, since last 3 years. I have done more than 15K in last 2 years. I had to get the new spark plug and a new rectifier, as the older one was cooked.
The bike handles well, especially on freeways and long-distance rides. It is not tiring at all. The bumps are minimal. It is a little sluggish in the city conditions at low speed. I have the same exhaust, as yours. But sometimes have a little heat buildup on a hot day at slow speeds.
