My old a$$ is having a hard time riding my 02 F4. I feel like I need a prop rod to keep my head in the look foward position. I read many old threads regarding raising the bars. It seems the only 2 choices I could find are the Ferracci risers and bars (or just risers??) or later F4 1K clip ons. Can anyone comment on which is more effective in positioning the rider a bit more upright?? Thanks.
