Have any of you guys put lowering blocks on the back without lowering the front ?? Any Problems or what ?

 

No but I had 11 shocks in back and std. hgt. progressive springs up front for about a year. Handled slower but fine, I've since gone to 11.5" shocks last couple years and lowered my front 3/4" sliding the tubes up in the trees for quicker steering and a more level look (I did not like the rake angle and it caused me to scrape my pipes more when I had shorter rear shocks).

 

yes and no

 

I machined some lowering blocks after looking at some. I loved them. I couldnt really tell anything was different except that I was closer to the ground. But, something kept squeaking. I checked out all kinds of crap. Finally removed the blocks and no more squeak.. Now that being said, they were homemade. I'm going to adjust them but for right now mines back to normal. Long story short, I had no handling problems. Get em.

 

I just put 3in lowering blocks on mine. I love them ...my bike has a tall seat so they helped alot. handling has not been affected IMO but i have ridden alot of slammed bikes

 

A bro of mine has them on his scoot. He says he loves them.

 

Generally speaking, lowering the rear will increase the front end Trail dimension. An acceptable Trail dimension usually falls within a range and varies based on the bikes design. As an example only, your acceptable trail range may be from 4 - 6 inches. As long as you stay within that range it's considered safe. Outside that range the bikes handling characteristics become dangerous.

Increasing Trail (lowering the rear end) improves front end stability at higher speeds and decreases slow speed steering response. Raising the rear does the opposite.
