It depends on which brand of eo u use.. Every person will give different interval if u ask around.. If you're used to ur bike, u can probably know when need to service as you will feel some harshness during gear changing.. Then it is the limit.. I have tried -
1) Kawasaki fully, just 3k+ km already need to change.
2) Then one more time (I forgot the brand coz it's my second time service) semi-syn, 1k km I go change already.. Very bad quality oil.
3) Rockoil semi, 5k km still good but I changed it anyway..
4) Now I stick to liqui-molly semi and 5k km service interval (still good also, but I think 5k km is good enough so I change anyway)..

Regarding tires, I just changed my 3rd set -
1st set Metzeller M5 (soft compound) - Rear 8k km, Front 19k km.
2nd set Pirelli Angel ST (hard compound) - Rear 16k km, Front 5k km still got 90+% left (I changed this at 5k km to match my rear tyre)
3rd set Metzeller Roadtec 01 (hard compound) - Just changed rear and front, using now.

Yea saw on other post manual written 10k or 12k km, but I doubt anyone following it.. Mainly due to different quality of eo, so it's hard to follow exactly in the manual.. Even their own Kawasaki eo is not meant to last so long (but it's cheap anyway).. Liqui-molly I'm using is rm48/btl, needed 2btl.. BTW, I think should be OK to run it till 7k-8k km, just that I never tried stretch so far yet.. Will try to do someday.. Coz currently I still feel 5k is reasonable enough for me..

I think numbers of cylinder plays role there? Coz as I know XJ6 also 3.4L despite slightly smaller cc.. That is one main consideration I put in besides the bike price before I decide to buy my er6.. Haha... Use it mainly for daily commuting replacing my car.. Ended up I'm enjoying my bike more than my car.. Since one year of owning this bike, my car just clocked in at 2k km... Wasted my fully eo.. haha

I'm using 15w-50 coz mainly is long distance.. The Roadtec 01 feels noticeable better than the Angel ST in wet condition.. As these few days keep raining, tested it a lot... Actually I changed my rear on Monday, yesterday only go change my front eventho still got 90+%...

18k km only? Told it was supposed to last longer... Anyway, this grip is good enough for me atm... Not really an aggressive rider...

My previous Angel ST lasted around 16k km with around 10% left... I was told Roasted 01 is way durable... Think I've been conned... Haha... But anyway, no regret... Just did a Cameron ride yesterday thru Sungai Koyan and it serve me sell... I try stick to recommended pressure @ 32f/36r... Tried go higher on rear last time @40 but it makes the tyre become squarish faster...

Phone auto correction haha... Ya I was actually asking for roadtec z8, but the seller say better use back Angel ST and save some $$ as Angel ST is slightly cheaper with near same performance... He said either take one step up to roadtec 01, or use back Angel ST... No point wasting money on z8... Still, most recommended is PR5 which is way out of my budget... Haha...

From the place I purchase, ST and 01 price difference - f = rm50, r = rm150 only... Which I think if 01 can get greater mileage, then the price-mileage ratio will be the same.. Not to mention better grip on the 01... So 01 will definitely be my choice...

Please update on any dedicated/new topic ya... Would be very helpful... Those are on my list too... Btw, heard T31 had great mileage too, but after 50% don't feel nice... Don't know how true was that...
