Reply To: Gt250/650 swingarm upgrade
Dare I ask ? What would be your personal advantages of using the 650 swingarm over your 250 one ?
If you use the rear 650 rim , 650 drum, it will cause your chain to bend side ways instead of being straight – The 650 uses 160/60 tyre and 525 chain
However your 250 rim allows 160/60 max – I would not go beyond this on the GT250 as the Ninjas of the same CC or ADV bikes use 130/140 rear tyre – Hyosung already gave us huge tyres in 150/70 lol
You are correct the spindles for the swing arm are for 650 frames only – The swing arm will get in the frame with some possible need of shims or spaces
The critical thing is making sure the shock is straight and not swayed left or right (lest it bursts when it goes up & down improperly)
Also chain is a critical thing , so for this reason we don’t use the 650 drums or rims = we leave that for the 650 engine and its chassis.
I hope i made sense 🤐
