Ducati Monster 696 is one of the most popular street motorcycles from Italian bike, Ducati, if you are planning to buy a motorcycle and if the Monster 696 is the choice, you should pay more attention to the Monster 696 specification, it's cause for 2011 Ducati Monster 696 and also 2010 Ducati Monster 696 has different front suspension type, 2011 Monster 696 uses Marzocchi suspension while 2010 Monster 696 uses Showa suspension. The difference of front suspension brands has showed on the Monster 696 specification on Ducati site.
Front suspension : Marzocchi 43mm upside-down forks
2010 Ducati Monster 696 :
Front suspension : Showa 43mm upside-down fork
Showa is Japan brands and Marzocchi is Italian brands. Both of suspensions are great quality motorcycles suspension and for me, Showa suspension and Marzocchi suspension are best motorcycles suspension manufactures.
Both of Ducati Monster 696 edition, 2011 and 2010 is still the same with 43mm upside-down forks, so i thing there is no significant difference between Marzocchi and Showa on Monster 696.
If you need more information about Marzocchi VS Showa, you should better visit their official website, or if you're Ducati owner, you can try to find more info about it at Ducati Monster forums. So, good luck for you and choose it by your favorite style and your favorite brands. good luck and hopefully helpful for all of you.
