Bike Model = : GTR/GT
Hello everyone,
Just wanted to ask what the common problems are with the GT and GTR as my friend is looking at getting a GT125 2010 and has asked me what problems it would have etc. He’s going to do a GTR conversion on it too so wants to put work into it. Same as me lol.
But yeah, any info would be greatly appreciated as can look into it on my bike too then 😉
TIA

Hmmm, ill update as i go along, but at the top of my head.
– Stock Regulator = Pimp it or watch it burn eventually and cheap China replacements are no better.
– Owners put wrong batteries = It uses YTX-14BS from factory. Owners put little scooter batteries
– Fried stators = because of regulator or owners putting Heated Grips when it doesn’t want it (KIES Heated gloves are better and have their own power bank to warm your hands)
– Stock tyres = suicide bricks in winter , but OK-ish in summer. Use michelins
– Forks pit easy (as with any bike with USD forks) , so split the forks and put gaiters for protection or Fork Seals will be your MOT worries
– 428 chain = Cheap for Korea to stick them on but bike is 180kgs, they ALWAYS eventually snap!
(520 is best)– Stock caps crack , so ignition issues (The plug hole is deep and very hot down there), we switch up to NGK ones one.
Bad caps ? ==> Your coils will die with them.Fork Gaiters (Yes fork gaiters) MUST be used to hide the 3 plugs under the airbox because the front tyre chucks a LOT of wet salty (soon cracked terminals and kill switch issues)
Like any bike, water and rain is the enemy => use gaiters to hide plugs exposed to elements , like your Stator Plugs behind rear shock
Like it’s GS500 sister, the swingarm uses cheap paint. Strip and re-coat with better paint.
Rear shock = Avoid 2010-2020 shocks, they ALWAYS bend. Any used 2003-2009 shock from GT125 or GT650 will outlive it! 03-09 have better shocks.
Calipers = Great stuff when they work, and also used on 650cc , so upgrade is OVERKILL, but pistons rust easy, so stainless pistons are recommended.
Brake Pad Pins = Get stainless pins (like these) , because sometimes owners replace calipers after damaging their old ones trying to extract a rusted pin.
that’s all i can think of for now
The bike will last as long as the owner stays OCD with it. I’ve had my own 2007 GT last me nearly 10yrs with mostly OEM parts still intact and did almost 60,000 miles. I went all over UK with it , now I ride the GV and soon a supermoto (Hyosung RX) if i can find it!
