Noob wheel question

I recently bought a drz400sm as my first bike. A lot of my friends have enduros and I want to get another set of cheap wheels to swap out for trail riding. How does one go about acquiring wheels? I’m big into cars so I understand the whole 5x114.3 18x9.5 +35 (as an example) idea. I understand tire sizes as well. The only thing I don’t understand is hubs and calipers/rotor sizes lol. Help a fella out!

TPI 300cc 2T vs 350 4T

Does anyone has experience between a 2 stroke 300 TPI vs a 350 4 stroke.
I am sort of looking for the ''perfect'' lightweight bike to switch between weekend offroad day(s) and weekday sumo riding.
Alot of forum topics are pretty old what I could find

Chain and Sprocket

Piston ring blow by (maybe)

Hey! I might not be using the right name in the title but this is my problem, I have a big 300cc two stroke and when I start it after it’s been sitting maybe 2/3 weeks and it’s real cold I see a bit of rings spitting out of the silencer but once the bike is warm it doesn’t smoke. Is it time to change the rings?

Worrying about oil starvation

Im looking at buying my first supermoto soon, probably one of the following, KTM 450, KTM 500, or a Yamaha WR450F. I am just wondering how worried i should be for oil starvation during long wheelies with these bikes as i see many influencers do these long wheelies without any issues but i also see online that oil starvation could pose a real issue to the engine over time. What bike would be the best that i dont have to worry about oil starvation during long wheelies ALSO without more maintenance than the average supermoto already needs (i know they already need a lot) Any help would be very appreciated

I need advice on exhausts

I need some advice on exhaust for my Derbi senda x-treme 2018. Currently it’s completely stock but I’m planning on switching the cdi and the exhaust. I’ve already bought a cdi but idk what exhaust to buy, I’ve looked at a Voca exhaust but that’s underlying and idk if it’ll fit

Please come with suggestions on exhausts under 200€ and advice on how to install it.

Also I can’t buy a faster bike because I live in sweden where I’m allowed to drive a bike that goes up to 45km/h but I’m probably going to make it go faster

Heidenau K80 vs. Pilot 2ct vs. GPR 300 - looking for street sumo tire that does decent in the rain and colder weather

Hello,

I'm picking up warp9s for my 690 Enduro and trying to figure out what tires to order. I'm looking for 100% street as I have the dirt wheels already.

I don't care about longevity at all, my main priorities are handling as well as good wet/ cold weather performance as I ride year round down to about 0°C so a soft tire with good siping would be ideal.

Three options I've found so far are in the title so I'm looking for feedback on them or other tires, I like the look of the Mutant but have heard the new ones are meant for ADV bikes.

Thanks

Turbocharging my 2023 KLX300SM

Does anyone know what all I need to turbo my bike? I plan to do a full turbo but I don’t know if it’s like a car where I need an intercooloer I wouldn’t think so because it’s a massive air cool system but maybe I’m wrong, I wanna know everything before I do anything and where can I find an external oil pump for the turbo or am I good to just use the bikes oil pump for the turbo?

1st Bike Advice: 390 or 690/701

Hello, everyone! New rider here. I’m taking a 3-day rider's course to get my license in a few weeks. While I’m a car gearhead, I have little to no experience with motorcycles—just some casual riding on dirt bikes and quads. That said, I’m confident I’ll pick it up quickly and become an avid rider.

Now to my main question: I’ve narrowed down the bikes I’m considering based on my lifestyle and needs, and I’d love some advice. For context, I live in Atlanta and will do mostly city riding for fun and short commutes during the weekdays (20–30 miles, up to 50 miles max ), along with more spirited riding on the weekends in North Georgia and occasional out-of-state trips throughout the year. Here’s my current list:

  • KTM 690 / Husky 701 SMC R / Enduro R
  • KTM 390 SMC R / Enduro R
  • BMW F450 GS

Me:

  • 5'11"
  • Weigh 175lbs, but typically weigh around 190 lbs (lost some weight from time off from a shoulder injury this year)
  • 34 year year old male

Here’s where I’m at:

  • I know the KTM 390 models are still a few months out, and the BMW F450 GS won’t be available until mid-late 2025.
  • I’ve heard it’s better to buy an Enduro and convert it for SM use (and back again) rather than converting an SM for off-road use. Thoughts?
  • I’ve read mixed reviews about starting on a 690/701 versus a smaller bike like the 390 or 450. Would I outgrow the 390/450 too quickly and regret not going straight for the 690/701?
  • If I wanted to be overkill on "safety" I could slap an A2 tune on the 690/701 to limit me as I grow accustomed to the bike and riding in general.
  • Pricing considerations:
    • KTM 390s are ~$5,500–$6,000 MSRP.
    • BMW F450 GS should be ~$8,000–$9,000.
    • KTM 690/701 is $12,999 new, but I’ve found deals around $10,500–$11,000.

I’d love to hear your opinions on these options and any advice for a first bike! Thanks in advance!

Husky 701sm - lower seat options

No matter what bike I ride, I strongly prefer "sitting in" the bike vs "on top". The overall height of the bike doesn't matter regarding flat footing so this is purely regarding the seat dimensions.

I've read that the stock seat doesn't have much pad material in the first place, so cutting out material won't make a huge difference. From my slight research, aftermarket seats are more geared towards comfort and keeps the stock seat height. Has anyone looked into this and found any feasible options?

50cc Supermoto

Does anyone here ride any 50ccs?(88cc-95cc upgraded) I’m looking to buy one and I’m thinking of getting a Sherco, beta, or fantic but don’t know what to get, also getting an upgraded cylinder and piston and exhaust because they are to slow stock.

2007 Crf450x blinkers

Hey I just got a 2007 crf450x that's street legal and ready to go, it has blinkers in it but they don't blink they just change the light to an amber color, I'm wondering if there's any good kits out there for some better blinkers than these led light strips that are in the handguards

Hat KTM sie noch alle?

Also ich hab mich ja schon lang gefragt warum es keine normale straßentaugliche, vollkommen legale 15ps 4t enduro von ktm gab. Naja egal aber was ist denn das?? Wie schafft man es, ne 152kg 125ccm ENDURO zu bauen? Das ist quasi ne Beta 125lc mit nem Sack Zement ab Werk hinten drauf. Das ist wirklich unfassbar schlecht. Die 390 wäre interessant als supermoto gewesen aber beim gleichen Gewicht wie ne 690 ähm... hallo? Ich weiß ja nicht wie ihr das so seht aber ich hätte mir ne 390 r/ sm gewünscht mit ca 30- 35 ps und ca 130-135 kg. Quasi ne legale exc mit weniger leistung aber auch nicht viel mehr gewicht. Aber was soll man damit anfangen bitte? Da komm ich wirklich nicht dahinter für wen sowas interessant sein sollte, oder bin ich da auf nem falschen Dampfer unterwegs?
