MX sir .. i just installed it yesterday 15/40 428 all sss brand :)
Tips: if you are still in experimenting stage you can just buy cheaper sprockets until you find the right sprocket combination then that's the time for SSS or other quality brands.. :thumbsup::)

15/40 is lower than your stock sprocket ratio... if your weight is below 60kg then good for you.. else wasted money...;)

haven't tried that combination... since my weight is 80kg, i use higher gear ratio"low speed" sprocket combination... IMO on 15/40 you need more than a kilometer to attain your top speed...

I tried 14/40 but i found it very hard to rev up in 1st gear but i can feel the power when reaching TS, :/

15/40 = 2.67 ang ratio paps its lower than the stock combination with ur weight 75kgs.. i dont think the 5th gear has power to pull yourself.
even me im 75kgs with the stock sprocket combination cant feel the power of 5th gear. But now im on 14/42 and attain 100kph+ in just a second ; and planning to change to 14/41 later :)

i see, the reason i use the 15/40 because of many smx riders in our group use it for their short and long rides. Ill test the 15/40 combi for incoming short ride this weekend. Ill post you guys what is my feed back :)
