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.

Item arrived quickly, with everything needed. I was sent a 13 tooth front sprocket. Have had it installed for a few days and can say while I have not seen the full speed increase (my daily commute to work is along a road with many declines and inclines) I can say that my commute is a bit quicker with this installed and I have seen higher average speeds overall. Also taking off from a stop feels better with the kit installed too. Have seen about a 3 to 5mph (speedo) increase in the gears 1-4. First time installing something like this I had all the tools needed (torque wrench, impact gun, socket set and hammer) had it done within 2 hours having read the instructions the day before so it was a straight forward and logical install (mostly need instructions for the torque specs). Only thing I had help with was holding the rear brake while torquing the front sprocket nut. Only complaint about the kit on my bike with this is that the chain adjustment needed to be set close to the maximum adjustment to remove excess slack in chain. If I have the bike when it comes time to replace the sprockets I will be purchasing this kit again.

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

This little piece is beautiful! I went for the gold, and really adds a nice pop of colour to the bike, so now I need to add some more gold to tie in!

Installed on RC 2018. This will be longer than most reviews but want to get all the details down to help you guys decide. Ladies and gents, the big ticket item on here for the GT family. If you enjoy performance and speed, then my god is it worth it. The damping and preload makes bumps and crests effortless, no bottoming out and chain is free to do it's thing. I have managed to test it here in Ulster on the road race tracks (not when closed roads sadly) and it performed like a dream, ride flows from section to section, cornering is massively improved, I can't fault it. Adjustment is relatively simple, I'm 85kg/6 ft4 so some adjustment/firming was needed out of the box, but all very straightforward, plus a higher set ride height is noticeable for me. Installation is one for one with OEM, would recommend mechanic there to give the bones and links a once over/lubrication and for an extra pair of hands. It is a larger price tag, but it's not everyday we get a company like YSS making a specific product for Hyo's. If you are on the fence, then definitely go for it.

Where do I start? The beginning I guess 😉 I bought this Beauty, a GV125-S last Month and was not happy with the Power and acceleration, or should I say missing Power of the 14 PS compared to my last ride a Yamaha XV 125 with 11 PS. Dont get me wrong I noticed the difference, but she was just laggy, screaming at me, and the Vibrations when going above 8000 Revs. In 5th gear she hit 10-11000 revs and just stopped power wise, not going any faster than 105 Km/h on the dial. In the German Group on Facebook it was suggested to upgrade the front Sprocket to one with 15 teeth, which I did, She run a little smoother through the Gears and the Engine sounded a bit quieter and wasnt screaming at me, but the loss in Power in the lower Gears, especially going from 2nd to 3rd, and the Top speed of 110 Km/h, which took me ages to get there, wasnt satisfactory, taking her up into the Red again to get here.. Then I saw Marcels post in that Group and decided to buy this Upgrade from the UK and have it shipped to Germany, thanks to Marcel here for the support. What can I say? I took her out on a 3 Hour ride to test, what a difference! The smaller front Sprocket (13) and the Larger Rear Sprocket (Dimension) and 520 Chain is the perfect combination. She shoots up through the Gears, no Jerking, no screaming Engine, next to no Vibrations, just smooth and fast, at 9-10000 Revs in 4th Gear she hits 100 Km/h and in 5th I had her at 120 Km/h and felt like there was still more .... plus it was a windy day 😉 I also ordered the NGK Spark plugs and HT leads which just finishes off a perfect combination. Thanks Marcel and Team, Season nears its end and I just cant wait to get out there next year, the Bike is so much fun now and I dont miss my Yamaha at all 😉
