[@mikey_bb]

As much as I absolutely love my 890R, I fear the pricing is way off for this 😬 realistically its £13.8k with the tech pack (the 990R will no doubt be closer to £15k). Looking around today, whilst my 890R was serviced & I can get a brand new 1290R with tech pack for £13.8k or a 1290Evo for £14.5k (their new 890R was £10.8k with tech pack, £10k without). I know the 1290 will be 'outdated' when the 1390 comes out, but come on it's a hell of a deal & 4yr factory warranty too!

[@10secondsrule]

It’s kinda of ironic the more speed limits go down the more power bikes get and there’s no more boring feeling than riding fast bike slow. 890 seems like a good bike for the road. I had Ducati s2r 800 in the past and I had so much fun riding it. Replaced with a brand new street triple in 2007 and what a boring bike that was in comparison. So much better and faster for sure but so much less fun (without getting into trouble)

[@brothermist0]

Absolutely. This comes to about 16K usd, the 990 R will be 17K+ usd. 2023 Super Duke Evo's can be purchased brand new right now for exact same price as the 990. This is before the 1390, after the 1390 is announced the 1290's will be FAR LESS than the 990 non-R.

[@sambagogo777]

"I can get a brand new 1290R with tech pack for £13.8k or a 1290Evo for £14.5k" Where from? The regular price (when including the current £3K discount) is £14.9K and £16.6K respectively so I'm keen to know how you're getting those prices!

[@thepongopete]

Let's hope they've addressed the build quality and reliability issues of the outgoing model (probably not)

[@Eksistenssi]

KTM originally took off by making (almost) ready to race bikes with better reliability (+ limited warranty) than modified yz/cr/rm with almost the same price. Now you have to pay more, have to fix the known problems before you start riding it and the "race readiness" performance has diminished by quite a lot and might be worse if you just upgrade other bikes with the amount of money you saved off from not buying ktm. I wonder how long is this going to last.

[@thepassionofthegoose5472]

In the market for a middleweight. My concern with KTM is build quality, full stop. I had a 1290 SAR that was an absolute lemon, so it soured me to the brand. We have ST 765 RS Moto2 editions available in the US, often at below retail. I'll likely be going that route. Cheers.

[@cribs4551]

Me too, my SDR 1290R was also a lemon, costing me approx £300 per month for the 12 months I had it. Before that I had a 990 SMT and the head bearing failed at under 3 months old without wheelies. I got annoyed with the 1290 and got a 390 Duke for the morning commute and for the 7 months I kept it, it would stall on every ride until it was up to temp. Most often in corners or on roundabouts. Such a shame…. After a 3 year break I got a 790 Duke and didn’t like it much (can’t explain it, snatchy and temperamental) so went back to the dealer who didn’t want it because he had a shop full he couldn’t get rid of at almost half price 🙈 I will not have another. Everyone needs to walk their own journey but there’s mine. Could’ve bought a top end bike at twice the money and been better off in the long run. Maybe…

[@moulip]

Hi guys, have I understood the price correctly ? 12990 £ ? Which are nearly 15K euros 😯😯😯 So if an R version should come, it would cost around 17K euros ? Are they crazy ? I was waiting for this new Duke 990 and more specifically the R version to replace my 890 R but I think I'll go for a used SuperDuke R or the new MT09 SP. What a shame KTM.

[@brothermist0]

2023 SD Evo's are being sold right now (in my area) for the same price as the MSRP for the 990 Duke non-R. Wait 'till the 1390 is announced & winter hits... They will be sold brand new, with warranty, for FAR less than the 990. Pricing is just dumb.

I owned two 990SD and one SDR. Those had 18L of fuel and no bullshit ride modes. Only thing I really want was the old SDR with a pillion and ABS. Maybe I'm getting old. Styling is pretty much Superduke astetics which is good.

[@TroyHarrison-d9t]

ill keep my 890 thanks, most fun, agile bike since my rgv 20 yr ago

[@yonniboy1]

I'm confused what now classifies a bike as a middleweight, the 990 is obviously a litre bike and the Street Triple is a 750 (ok 765) but surely both can't be middleweights, are we gonna have to rate them like boxers, middleweight, super middleweight, light heavyweight......?

[@hossman8499]

Hopefully they redesigned the exhaust header. The 890 has issues with the thermostat housing leaking. Im guessing its due to it being about 2 inches behind the hot ass header and being made out or some sort of plastic.

[@shibapatrol801]

It's expensive and it has demo mode that locks buyers from accessing features on the bike lol. KTM has absolutely lost their mind if they think this is acceptable given their reliability reputation lol.

[@bitzannbobz]

[@exothermal.sprocket]

Remember when motorcycles had a cable from the grip to the engine throttle? Remember when they were scary to ride because there wasn't bubble wrap between the rider and consequences? Yeah those were interesting times. Now we pay massive amounts of money for a strong bike, pay even more to turn on electronic nannies, and even more to remove restrictions and give us the actual power. It's like you gotta pay another 1/3 the whole motorcycle price to peel back all the layers of the engine onion and see what's actually under it. Now manufacturers are putting traction control on 400cc bikes. WHAT KIND OF POPPYCOCK.... Manufacturers stopped innovating many years ago, and now all the technocrats have taken over the firms.

[@BigCarKilla]

Why does KTM do this?!?!? They did it with the 890, introducing it shortly after the 790 - not even letting it ride out some sales before pumping out the replacement. Ah well, I do love me a constant improvement.

[@turkishexpress]

With these new anti-wheelie electronics, if you set it to the medium setting and just grab a bunch of throttle, is it going to hold that wheelie or just do a sudden drop? Asking for those of us that are wheelie handicapped lol.

[@TheAsheybabe89]

Idk about this bike. But a lot of bikes will kind of skip the wheel. It really depends on how aggressive the wheelie control is set. Some will cut power before it ever comes up, others will cut power just as it comes up giving you a sketchy feeling skipping front wheel. I'd rather nearly loop the bike grabbing a handful of throttle with no wheelie intervention than to have it skipping the damn wheel everywhere begging for a tank slapper

[@turkishexpress]

@@TheAsheybabe89 I agree with the older electronics hence my question. I have a first gen 1290r and the wheelie control sucks. It abruptly cuts power and dumps the front wheel like a lead weight. With newer electronics, they have the ability to set an angle and modulate ignition and even rear brake to keep a wheelie going. Granted this may create a legal liability issue.

@@kleinbottled79 nah man. Look up.some Dyno/tuning videos (Moore Mafia has one).

It's biggest selling points seem to be sound and Yamaha cultism lol.

[@kleinbottled79]

@@TheAsheybabe89 140whp sounds about right for a claimed 160 at the crank. Did just look up cycle world's Dyno number for the super duke and they got 161 at the wheel. So yeah, a 20hp difference and both are far more than enough. IMHO the cross plane sound makes up for the iffy looks and Yamaha reliability more than makes up for the 20hp. So in a sense you are correct on the selling points for me personally.

[@kleinbottled79]

Also, if we are going to get into the weeds on these bikes, I prefer the handling of the MT10. The R1 derived chassis giving great confidence especially in the front end. So locked in. Super Duke is more nimble but less stable. Both great, only slightly prefer the MT-10 in this. And both are quite comfortable too. Edge perhaps to the KTM there.

Had a shot on the 890R last year and I was really impressed with it, I think this will be even better. That said I'm happy with my 1998 CBR 918 RRW. A little bit heavier (not much) steers super quick, more power slightly, smoother engine, is cheap to insure, looks great, has a decent fairing, sounds ace, and that's a 25 yr old motorcycle. I like this new KTM I really do, but I also like my CBR and it was paid for years ago. These software upgrades, you don't need them you don't.... they're selling them to you and it's money for old rope, but you feel pressurised into buying them because it affects your resale value, and that grips my sh*t a lot. That said if I was feeling flush I'd deffo take this over the 1290 though, I think it's the better bike, that's just me though, the 1290 will always sell more because willy waving is a thing.
