Bonniebird Posted October 17, 2013 Share Posted October 17, 2013 I should be getting my Speed Four at the weekend and I intend to lower it as I'm only 5'4'' (and a bit) and the bike is a bit tall.I've already bought a Lust racing lowering kit for the rear suspension linkage which lowers the back just over an inch (30mm)What should I do with the front end? Drop it or not and if so, by how much?Various websites seem to have conflicting advice - the most likely advice seems to be drop it a bit but not as much as the backShould I just see how it handles and adjust accordingly?Plenty of horror stories about lowering - tank slapping and the like - but it seems a pretty common thing to do to themBTW - also thinking about a conversion from clip-ons to flat bars Quote Link to comment Share on other sites More sharing options...
Stu Posted October 17, 2013 Share Posted October 17, 2013 I would leave the front and see how you go! if you do drop it through the yolks then yes it will make the front a little twitchier and it will also turn in quicker if you feel you have to drop the front then you could always fit a damper.....also a lot of tank slappers are caused by poorly set up rear suspension Quote Link to comment Share on other sites More sharing options...

In theory, the front should be dropped to maintain the wheelbase - it's dead easy to lower and raise the front through the yolks so if it handles like a dog to start with you cam just pop it down a bit and see how you go!

Bonniebird Posted October 17, 2013 Author Share Posted October 17, 2013 I'm inclined to leave it to start with and see how it goes.The suspension is highly adjustable on the S4 so may be able to compensate for changes in dynamicsSame with the side stand - I'm hoping to get away with not having to shorten it - I think the bike leans quite a bit on the stand so it may be OK.Going to be fun setting it up Quote Link to comment Share on other sites More sharing options...
megawatt Posted October 17, 2013 Share Posted October 17, 2013 What Stu said. Just lowering the rear will make the bike more stable , but will slow the stearing a bit. Never had any issues when I lowered the rear of my Bandit 12 by 3". If you must lower the front, I wouldn't go lower than 10 to 20mm, but I doubt you will need to.

Bonniebird Posted October 18, 2013 Author Share Posted October 18, 2013 Would get 2nd hand side stand off ebay (other online vendors are also available) to shorten and keep the original with the old suspension linkages in case I sell Quote Link to comment Share on other sites More sharing options...

Joeman Posted October 18, 2013 Share Posted October 18, 2013 See how you get on before messing about with it.I'm 5'10 and no way I can touch the ground with both feet on my KTM - I Dont think anyone could as the ground clearance is far to high, but didn't take long to get used to.
