I did 200 miles on the bike the other day and I'm sure 80mph in 6th is 4500rpm, but feck me its drinks fuel now and it's very naughty, We compared the gearing to my mates 1050 adv and speed to rpm is exact the same.

Well here's my thoughts after 1,100 miles and a selection of roads from motorway to very tight bumpy back roads on Irelands Wild Atlantic Way.

It's a vast improvement changing to the 40 tooth rear sprocket. The bike is now happy at 80mph in 6th gear and responses better in top gear so makes motorway cruising far better. It's livelier everywhere else in the gears and rev range.

Speed testing on a private test track resulted in 164 mph on the speedo which shows as a genuine 157 mph on the sat nav at 9750 rpm. With a bit more time and effort I reckon it will reach a genuine 160 at close to the rev limiter. Wearing leathers instead of textiles would help as well.

Fuel consumption was pretty horrific in the low 30's when caning it and cruising at 130 but actually better at sensible speeds with upto 45 mpg which is my best ever, probably as I found it easier to run at a more comfortable revs than before when it was either revving a bit more or lugging.

So I'd say it's a definite hit

Who's done front sprox mod !

Post by MR C » Tue May 16, 2017 12:50 am

So over the weekend I took my 40 off and put on the 39 tooth sprox I had been running previously, for comparison the 40 is a great upgrade however sitting @ 70 the difference is 500 rpm between the 39 and 40, fuel consumption is very noticeable with the 40 and I do like the instant pull in any gear with the 40 fitted, 6th is deffo more suited to the 40 tooth sprox but 39 is a good compromise and the power out the bends feels more linear whereas the 40 you need to have massive balls to give it plenty when your coming out the bends, another downside with the 40 is the idiot light keeps flash because it will lift the wheel way to easy.

I let my mate ride it back and he said it felt scary, a tiny bike with way too much power and he refused to ride it hard.

Hmmm, so the choice is :evil: with the 40t and :) with the 39........ decisions, decisions, groan...... but I do like the suggested compromise with 39t....... I don't want to gear down too much....just enough to help 6th on highway cruising......at the moment I just treat it as a 5 speed box (unless I have a downhill with tail wind).

Thanks MrC and BDG......I look forward to your thoughts as you do more miles........ :)

Ps I know DaveNz will be happy.......anything that makes the front lift and lights flash will please greatly ;) :lol:

Im still waiting for my sprocket to turn up Dave, its in the country tho, please be here by the weekend, sunday looks like a sunny still day, good for testing. And No Dave, no more red and blue lights, ill stick to hooning on the back roads. I wonder if you would really notice 1 tooth less with the 39, i think there will be a better gain with the 40, and can always switch back to the 38, as i find the 38 pretty good all round, except for 6th, thats a 100mph gear.

One tooth doesn't sound a lot but lay the upgrade sprox over your stock and it's very clear how much bigger it is. I think you will like the 40 it's a good mod and the get up n go is very impressive, I'm off to Spain in 2 weeks and the way it started to drain the tank with the 40 fitted would not be ideal for a 3k trip.

And thats why i think the 40 is a better choice MrC, with the quick change sprocket setup on the GT, its quite easy to swap sprockets. 38 tooth for touring, 40 tooth for fanging it. Im also looking forward to seeing how the quick shifter works with the smaller steps between gears with the 40 tooth.................PS, my sprocket has arrived (YA) and so has the rain. fuk ya can't win trick..........Ok 15mins and the 40 is on, and i can see some sunshine peeping from behind those black thunderous looking clouds.

Ok Dave, last time 5th-4000revs=100kph, now with the 40 tooth, 5th-4350revs=100kph, so it seems not a large difference at 100kph, but 200kph it would be around 700revs more, and that will give the top gears more drive higher up the rev range. as for the 40 tooth, its a pleasant surprise, it does make the quick shifter smoother through the gear changes, (it was smooth before, but it has improved on that) acceleration through the gears is more rapid, so suits the quick shifter better, I'm now using 6th a lot more, so i doubt there will be much change in my gas consumption, i think you need the 2 tooth change to get and apprieciate the gearing change, i also think going the 40 tooth rear sprocket is a much better way than reducing the front sprocket to a 16 tooth (which would equal a 41 on the rear) i think thats going too far on a torque monster like the 1290. all in all I'm bloody happy with the extra 2 teeth on the rear, definitely a positive up grade, my bike is getting closer to perfection. :P

Cheers mate, that's great intel......350 rpm is not too much extra ( I had figured approx 250rpms but what's 100 more :lol: ).......we don't have any 80mph (what's that in metric speak...130kph) Autobahn's or motorways here....though on lonely country roads those speeds might be used sparingly, but only when necessary, officer, honest, true....etc etc

Hey get this, the force has little 6x4 yellow box trailers with a periscope and a birds nest on top......it's a relocatable speed camera.....looks a bit like a roadworks night lighting genset.......gotta keep the eyes open here in Ausland..... ;).....these things and the R1200RS/Hayabusa/R1200GS/GTR1400/etc with little speed radar's bolted to the RHS mirror mounts and pretty blue & red flashing christmas lights hidden inside fairings......only way to pick them is the riders all use plain white helmets with a tubular go=pro type camera stuck to the left side and a bloody great big gun in a holster hanging from the right hip.......darnit, now they'll wise up and go flash colours etc etc.......so no racing that unknown rider that just appeared behind eh ;)

Hey DavennnnZ, just back from a 600km day ride ......ws thinking about the 350rpms as I was hunting through the Bruxner highway's corners and climbs......and I think you are right.....the extra 350revs in each cog would help as I was often in 4th holding 100kph uphills and 5th wouldn't hurt spinning at 4500-4600 at 100kph instead of 4-4250 and wanting a change down to 4th on every uphill......

Question.......did you buy the alloy sprog's Mr C was using? I'm assuming they are nice and round (you would have mentioned if there was any quality issue ;) ) so I'll get tapping and order one soon......MotoGP telecast is on now......gotta go.......been a fab day fangin through the hills.....fek.....Jack Miller's crash......wow..... :shock:

I had a great day out on the GT yesterday also Dave, the day, like today started with a big frost, then a cool crisp still day, but not a lot of heat in the road surface. And i ve got to say the 40 tooth is perfect if your doing lots of windie back roads, and you still have 6th for the open roads. Hey i brought a steel sprocket out of Germany, found the site on eBay. ill be back in a sec with the site. Hey i also swapped bikes with a mate, i road his 1299S, with a full Acra race system, bloody nice bike, but no way would i swap bikes, after riding the full TTX electronic suspension on his bike, it made me really appreciate my suspension (Sports, rider with luggage) he liked my suspension also, after riding my bike then jumping back on his, he realised how hard his bike rode. I found his bike felt right once doing 160Ks plus. But man i loved his auto down shifter, gee it was amazing using it, it seemed it didn't need brakes.......OK 40 tooth steel black sprocket info@kettenmax.de I went steel, its more proven with the big torque of the 1290......MR C tip on fitting the chain over the sprocket worked a charm (Thumbs up C) i used the adjusting tool supplied, slackened the chain max back, fitted chain over sprocket fitted 6 bolts, then need to tighten the chain only a little, so there is room to adjust out the slack, so 40 T fits easy.

Cheers fellow Dave - oh fek Moto3 crashes made the evening news.......and MotoGP Marqez/Rossi crashes......bloody amazing, bike racing on the evening news :o .......what's gone wrong with the world?........are all the journo's out of work already and 'big news' are looking for spectacular footage??

Ohhhh, tried to get Kettenmax to like me but they don't have Aubloodystraylia listed on their country selection so I couldn't register.......bugger....... Those steel sprox are either JT (good brand) or the major Euro brand which would be equal quality.......but I couldn't get the site to play ball - what am I doing wrong? I thought I'd see what freight cost and maybe order both 39 and 40 teeth......though the 40 is all i need....but can't even register....... :(......sh t bugger bum...... :roll:

Will try again later......maybe better luck later....

Cheers mate, I had identified the sprocket from the Kettenmax site (JTR893=38t.....but couldn't select the 40t as the site suggested....). I guess if I am able to get to the cash register I will have the option to specify the tooth sizes and get a freight/postage quote....... :idea: .....maybe I shouldn't try to register and just go to the checkout first......hmmmm.....I'll have another go... :roll:

It may be that the site is offering free delivery for Euro customers, and I am blocked from access.....or there could be an Aus agent and I cant go behind their back.......but who the fek are they????......grumble :lol:

Thanks mate.......I've given up with the http://www........ for now. I think something has been done to Aus so we can't buy direct from O/S......like we did with our Capo12 bits instead of paying high local prices and waiting forever for delivery.

Hopefully 'Metal Gear' will read last nights emails soon and track down a supply of 40t sprockets from either Esjot or JT and update their website.......and sell at a nice cheap price :lol: ......looks like I'll just have a 5speed GT to ride for a while longer.......the local industry in Aus is F'n hopeless...... :roll:
