Upgraded the chain and sprockets on my GV 125 c, to the 520 chain, and what a difference it makes. From pulling away for the first time after fitting the differene was clear. Smoother and faster transference of power to the back wheel through the gears and fourth really does feel like fifth. Really happy with this feels like a new bike. Cheers Marcel 😛

Get these NGK HT Leads everyone, in Combination with the Laser Iridium Spark Plugs, it makes a difference, she runs a lot smoother, better Throttle control and idle

An absolute must have, making life a lot easier to work on your engine.

It really does make big difference I’m just not sure about the front sprocket Because I see the one on shop it has 14teeth I recited 13teeth But I’m very happy about this upgrade Thanks Marcel

Big shoutout to marcel for the coils, ordered and delivered in 3days all in time for the new year, also went for a 3hour ride after fitting them along with a service of course and she’s not skipping a beat no more 😁 definitely recommend for anyone on the search for parts

This is an absolute must have for your Hyosung! Had it for around one year now, and it works great.

It’s a very nice kit that includes what you need. I especially like that it comes with new screws!

Been driving with this for about one year now, and it is amazing how these changed the spark characteristic on the bike. Great product.

Iv only ordered this as the old ones are rubbish

Logged a few hundred miles since the upgrade. Here are my thoughts.  This brake system upgrade is the best value for money spent since I bought the bike. Dramatic improvements in overall stability, high-speed handling, and low-speed manoeuvring. The Hyoriders club may have saved my marriage.  This is my third attempt to write a product review for the stainless steel braided brake lines. Hopefully this time when I'm done I don't hit the wrong button. I don't really do product reviews. Either the thing works as advertised or it is sent back.  I am taking the time to review the braided brake line kit because Hyoriders shop has been the best customer service experience in all of the thirty years I have been riding motorcycles.  I ride a 2008 Anniversary Edition GV650 efi. It was love at first sight and I paid cash-in-hand. Soon after it became apparent she had not been properly maintained by the two previous owners. I struggled for ages to find legit OEM fitment parts & upgrades. So much so that I've been ripped off by a couple of sites claiming to be licensed distributors.  Hyoriders to the rescue.  There are plenty of bad faith actors out there and my wife and I are really glad I found this site. There are loads of tweaks and mods that provide wee little improvements in performance.  I do love my X-Ring chain conversion and everything else I've bought here.  However, this brake system upgrade is the best overall performance per pound. I now know that if I can only afford one performance upgrade on a bike that it will be stainless steel caliper pistons and steel braided brake lines. It really isn't possible to explain just how much better planted it feels in the corners or the effortless low-speed city street and/or carpark handling. I could try to remember everything I said the first couple attempts to write this review, but I'll just leave you with a couple of observations.   Caution: Take the time to talk with your mechanic to clearly communicate how you want the brake lines routed. Ensure you have all the nylon P-clips or zip-ties, or whatever mounting hardware you prefer for your desired finished look. Confirm with the mechanic where the lines will be routed and how they will be attached. Five minutes, or less. That's all it takes to be certain it looks the way you want.   Also,  Are you running OEM or after-market / reproduction calipers? If so then please ask about a stainless-steel caliper piston rebuild kit to go along with these awesome braided brake lines. Sincere thanks to Marcel and the entire Hyorider team  -- Cheers, Chopper Pearson In all things, Endeavour to Persevere
