16T KTM rubberised sprocket
« on: January 06, 2016, 06:13:25 am »
Hey all,

Just my FYI, I purchased a 16 tooth KTM rubberised front sprocket and exchanged it it's the stock 15 tooth leaving the stock 45 tooth on my 2015 690.

The change was very easy and took 15 minutes.

The characteristics of the bike after the change is awesome, now she rides like a big bore should, I ride high speed dirt roads and our highway speed limit is 130 kph.

Now she cruises at 4000rpm at 100kph whereas with the 15T she as at 80kph.
Now at 130kph she's running at 5000rpm.

Yes it's increased 1st gear speed but not as significantly as I was expecting, the best outcome is how each gear pulls longer so I'm not having to quick shift through the gearbox anymore.

I've ridden in the USA Michigan trails before so I know how a 16t wouldn't favour single trail, but for anyone that finds the stock gearing too sprinty and restricting, I think you will be very happy with a 16T.
I'm not as good as I once was, but I'm as good once as I ever was.

Good info - do you have a part # for the 16t?   Was it KTM part, or other?   What was the increase in your MPG (fuel efficiency)

I'm currently running a 14t non-rubberized aftermarket (=cheap) - but I do more trails than road right now.   OEM 15t I was getting 'about' 50-54mpg.  with the 14t (and whacking the throttle off road) i'm getting about 40-43mpg.   Might be riding across the USA this year on the TAT and getting better mileage would be a huge plus!

Today I rode a total of 349 kilometres with the new 16/45'gearing, mostly on dirt roads, some bitumen and some tight single trails.

Firstly I was amazed at my fuel economy, my first refuel was at 218.5 kilometres and she used 8.52 litres, which is 3.9 litres / 100k's or 60.3 (US) mpg.
This is a theoretical 300 kilometres from the stock tank.

I wasn't out for economy records and I wasn't stonking along, just adventuring.

1st gear was good down to 10kph, under this the clutch came into play.

6th gear is now like an overdrive, for me 16/45 is far better than the stock gearing, but I don't do tight trails.
What I appreciated most is how my engine is now accumulating way less rpm for the same given distance.
I'm not as good as I once was, but I'm as good once as I ever was.

Awesome Roost. Good update, did you buy it at the place Philip mentioned in the other thread (Munnracing.com)?

I ride on the side of mountains usually so I went the other way with gearing to 14/46. However, there are some long rides in my future (finally) and that's good info. Think I'll source a rubberised 14t (current is sans rubber) and a 16t for the longer stuff. Thanks again.

Be nice to know a source for a ruberized 16.  I have looked online at most of my favorite sights and not located one.

Has anyone experimented with a Rekluse clutch? I was thinking this could be a perfect solution to having too long of a 1st gear while going to a 16T...
