I bought two of them but returned them because they don't have the heat shield provision.
The Sparks does,, as does the Yoshi.
To close for comfort with no heat shield provision. Your leg is inches away.
Stock YFZ450 pipe with heatshield.^^^^^
The Yoshi Pipe protector.^^^^^
Looks cool too^^^
Nasty burns from the pipe otherwise, or you may set your pants on fire. Read other posts here in YFZcentral of those who have. Any company not offering simple protection like this I don't want to do biz with.
