X LEVEL Swingarm 


Six 5 Design is proud to introduce our innovative line of Swingarms. Our swingarms are unique to say the least.  We have gone drastically against the grain when it comes to this area of our product line.  These Swingarms are a statement of individualism as well as to prove that lightweight components can be built to outlast and out perform the conventional (Box Tube Style) swingarms that have ruled the market for years.  

​If you have a YFZR, you know that there is an issue with the OEM Swingarm holding up to the abuse that a serious rider can inflict.  This swingarm is a direct replacement for your stock swingarm with a few important additions. 

It is made of 4130 Chrom-moly steel tubing,  formed into an arched style design for superior strength.  X brace with formed tube gussets for excellent load transfer and durability. 

We have also added a bolt on chain guide to ensure that the chain stays on.  It uses an OEM Honda Chain Guide off of a 1996-2001 CR250r and CR500r motorcycle. 

These swingarms are pounds lighter than the nearest competitor.
