TriGlide fork oil

[mkefe]

Has anyone changed their fork oil to a heavier oil to reduce some of the nose dive on the trike....just curious?

I never experienced much nose dive with the 2010 I used to own. If you go heavier on the fork oil it will make the ride harsher.

I agree ...never really have much nose dive on mine either. unless I am braking too hard..

How much nose dive are you having ??

Wow, HD Electra's are notorious for their ultra soft front end which begets plenty of nose dive when applying the front brakes. Fork oil only effects the rate of dampining and rebound. A lighter oil will pass through the valves quicker and a heavier oil will slow down the process in both directions. Heavier oil may slow down the nose dive but conversly if you are also slowing down rebound you may not have sufficient stoke available if you are going through a bunch of heavy bumps in rapid succession.

Progressive makes a Monotube front fork Cartridge Kit that I had installed in my 2011 Ultra and it was fantastic. Eliminated the nose dive and was excellent front suspension. Check the HDForum, Touring Bikes for more details.

As far as my TG, I don't really care that much about the excessive nose dive since I'm on 3 wheels and it's controllable. On 2 wheels the nose dive was a real pain when coming to a stop where the road was wash-board by heavy trucks.

I had my dealer install the Progressive Monotube Cartriges in my 2011 Tri-Glide when we changed to the chrome lowers and chrome front wheel. One of the best investments for the dollar in ride quality,handling and nose dive IMO. They are warrantied for life to the original purchaser and once installed, the fork oil never needs to be changed again. Hope this helps you.

Thank you for this info...I will consider this option.

I use Spectro 40wt fork oil for my trike. I change the oil every 2 seasons or 25k miles. On my Roadglide trike its much easier to do because I only have to remove the speedo nacelle to access the fork caps to refill them

If you decide to use this fork oil, you will have to order it from this website. Dealer who stock Spectro have to buy it by the case >>> http://www.spectroshop.com/suspension-fluids/heavy-duty-fork-oil-heavy-sae40-/prod_49.html

The valving in the shock will pass oil slower, but the rebound is faster than the up-stroke. Some valves are close to zero restriction on rebound. They aren't 50/50.
You can also change the oil in your rear shocks on the trike. It requires the removal of the shock to do it, but is well worth the effort in a lot of cases. Harley uses a very light oil in the rear. A little work on your part might give good dividends. Especially in the front shocks, very little work and not expensive to give a try.
BTW.... Measure the oil very accurately !! Also a Mity-Vac pump speeds up the change !
