RIDER FEEDBACK // SHOP REVIEWS
520 Upgrade Chain & Sprocket Kit Conversion Hyosung GV125-S EFi Bobber
Sheldon - GV125S EFI 2021 - UK
After a little bit of a struggle I finally got the kit on! Thanks to the forum post that front sprocket was a right ass to get off! The bike feels much nicer to get up to speed, it feels a lot smoother and nicer to ride! So far I’ve noticed an increase of about 5mph on the top speed but I haven’t pushed it to see how far it will go but that extra 5mph gives a more comfortable carriageway experience. Highly reccomend!
Upgrade Clutch Springs & Plates Friction Drive Overhaul Kit - Hyosung GV125-S EFi (Injected)
TomaszG81
Highly recommend to install this kit. The clutch reaction is much better, lever is more stiff, clutch action is more punchy. Super nice feeling when you change the gears. I have the impression that the bike is less jerky on 1st / 2nd gear when you ride with small speeds. I love the kit and I'd do that again without any hesitation

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

The best upgrade you can make on this bike. Those sprockets change everything - acceleration, higher max speed, better rmp/speed ratio. I'm super happy and I'd do it again, anytime. The only suggestion to Marcel I'd have is to offer the front sprocket with rubber to make the chain work quieter with less vibrations. All the rest, 10/10!
