Ducati Hypermotard 950 SP: Unlock Lightening Fast Acceleration

If you ask any motorcycle rider, the most common change after exhausts/remaps is sprocket/gearing changes. Usually dropping a tooth on the front or upping the teeth on the rear to improve the low end grunt, increase acceleration and have a more useable bike through the gears.
The standard gearing of 15T/43 is fine, but I've always gone down 1 tooth on the front to give the bike more character and increase the fun factor. The process is straightforward for any normal biker with a good set of tools (32mm Socket for the sprocket nut).
However, the Euro 5 bikes don't appear to like the change as it probably messes with some parameters that might make the ECU think they are out of bounds and hence flash the DTC/DWC and remove the gear indicator on the Dash.
It throws a P0919 fault code - Gear Shift Position Control Error, which doesn't really make it easier to diagnose. I found a google link to ‪@DeussenEngines‬ who may have a workaround - and hopefully ‪@BHPUK‬ can sort something out too.

I went 14/42 on my '22 SP, seems perfect (albeit slight), no codes - good luck, keep the vids coming!

[@hypermotardking]

sounds a good compromise.. hopefully got a workaround coming soon.

Long time subscriber, first time commenter! Love your work! Just to clarify and confirm for all the euro 4 guyand gal 5:29 s out there my 2019 950 SP has responded beautifully to the 14T front with no errors or dash issues. Left mine on the shelf for ages cos of dash fears but trust me, go for it and you won't look back!

[@hypermotardking]

Yep - 100% this is change you can do on the Euro4

[@beefabbear4104]

Thanks for the info man. I want to do the same with my SP2 to sort out that insanely tall first gear. Makes it a right pig around town. My dealer said the euro 5 bikes won’t recalibrate with lower sprocket and I didn’t believe them. Thanks for confirming. I thought they were just being w*nkers

[@hypermotardking]

There is a way to do it through the ECU.. German company Duessen Engines can do it, but you have to buy their device & map - and I’ve already got a custom map on mine. The bike still runs fine but just with a few orange warning lights on the dash 😭

[@tazpartridge1612]

This was my first mod, makes it more ridable around town, easier wheelies, not missing the top end speed. Didnt have faults, but mine is euro4 9:03

[@hypermotardking]

Yeah, appears the Euro4 range of bikes are ok. Heard someone with a desert-x tried same 14T and got same error

[@tazpartridge1612]

[@r1freak1]

Have you tried going two in the rear instead ? I was about to do the 14 yesterday on my 23 SP but I could not find an answer if the bike would not like that change, and then you uploaded with the answer I needed. I wonder if changing the rear sprocket instead to a 45 would have the same impact with the fault code.

[@hypermotardking]

The front was easier to do as a “quick test”. The rear +2 might need a longer chain and then more costs etc. Maybe a combination of both might work, but that were talking maths and rations 😭

[@nils284]

Hey Hypermotardking, the rear sprocket with 45 tooth won't work either on the Euro 5. Some tested it and wrote it in the german hypermotard forum. So dont try it, its not worth to buy a bigger chain and having the same results with the 14 front sprocket. Greets

[@hypermotardking]

@@nils284 Thanks for the heads up 🤛🏼

I couldn't help but notice the Big Orange ball in the sky where did you get that? The SF Bay Area has been foggy every damn day. Give us our sun back.

@@hypermotardking you need to try GP shift super easy to do with the setup we got they even gave you instruction.👍

[@maxbreemer]

I heard about the same problems on the Euro 5 Supersport 950 when tryign to gear it down with a 14T front. Was this ever solved by a third party? This would stop me from buying one...

[@hypermotardking]

It hasn’t yet by BHPUK because I not had a chance to get to them for testing - Duessen Engines has done it so its possible

[@sebakrarup]

I did the same on mine! I love it! And also i put 3 more tooth on the back sprocket! Cheers!

[@hypermotardking]

What year is yours? Did you get any errors?

[@sebakrarup]

​@@hypermotardking Mine its 2013 The 821cc, no errors!!! Stock gearing its 15-45tooth. I live at high altitude so its a must! Also i want to change my chain to 520.

[@sebakrarup]

Hope you can fix the error! Nice bike you have!!

[@hypermotardking]

@@sebakrarup Aahh.. your lucky. 520 pitch with lightweight sprockets is a good move 👍🏻

[@sebakrarup]

@@hypermotardking Maybe the error has to do with the quickshifter! My bike doesn't come with a quickshifter! Let us know if you fix it!

Only thing with these new bikes. You just cant change shit, withiut a cide error come up. Still a great looking bike 👌🏼👍🏼

Thank you very much, love the channel. Hope you get the dash sorted, here what about just doing the back sprocket to a bigger one and keeping the 15 on the front.

[@hypermotardking]

@@adrianmarsden2790 could do.. might need a bigger chain - may just try it?

[@PtDoughnut]

Have you heard of the Hypermotard leaking rust out of the tail all over the splash guard on the rear end?

[@hypermotardking]

I’ve only ever seen one post online about it. The rear undertsil unit isnt the best for keeping water/mud out - so its a possibility

[@PtDoughnut]

@@hypermotardking I had googled around about it, mine I have owned mine for a month and it started doing it almost immediately.
