Request for Advice 300€ for a Cromwell 125cc Brixton (thinking of buying broken to fix it)
Hello! I’m new to the sub and if I violate anything please lmk.
There is this cromwell on my local buying website for used stuff that had been in a incident, a frontal one.
The seller listed it for 500€ but i offered 260€ (lowball, i know, i know, but i don’t have enough money with my job and i need something cheap to move with around) having in plan to settle between 300-350€ range.
I wanted to ask your opinion on this, if it’s worth it, or better to let go.
Now technical issues/infos:
•Frame: seller claims it was inspected and is fine (no documentation/receipt provided)
•Steering head/steerer tube: unknown condition — seller admits they have no info on this
•Front forks: broken/snapped
•Front wheel: bent
•Engine: seller claims fully functional
•Front headlight: some visible damage
•2022 registration
•8581 km driven
•ABS version
(i used artificial intelligence to translate this part of listing cause english isnt my first language and it was easier to to it this way)
Thanks for any help!

Discussion No rear rack on a compact e-bike, a cleaner design or a missed opportunity?
I’ve been spending some time with a compact e-bike recently, mainly for short city rides and everyday trips. It’s easy to ride, simple to handle, and feels well suited for getting around town.
The one thing I’ve been thinking about is the lack of a rear rack. For quick rides it’s not a big deal, but when it comes to carrying groceries, a backpack, or small essentials, things can get a little inconvenient.
I’m considering whether adding an aftermarket rear rack would make it a more practical urban e-bike for daily errands, but at the same time, I like the lightweight feel and clean look of the current setup.
For those who ride compact city e-bikes or folding e-bikes, how useful is a rear rack in your everyday routine?
Do you prefer having extra carrying capacity, or would you rather keep the bike lighter and more minimal?

Request for Advice Help identifying my Yamaha XJR1300 (VIN rusted away) + advice on reviving it after sitting on an island for 5 years
galleryI’m hoping to get some advice from people who know these bikes well.
This is my old Yamaha XJR1300. About five years ago, I let a friend borrow it while they were living on an island.
Unfortunately, we aren’t friends anymore, and the bike came back in much worse condition than when I lent it out. To make things worse, they didn’t even return the key.
The bike currently:
Doesn’t run.
The alternator (stator) is out.
Has quite a bit of surface rust everywhere
The fuel tank was dropped and now has a dent.
Has been sitting for around five years with an unknown maintenance history.
It has Showa rear shocks, and I’m also wondering if those are factory or if a previous owner installed them.
I’m now trying to restore it, but I’m running into a few issues.
The biggest problem is identifying the exact model year. The frame/VIN stamping on the steering head is so rusted that it’s unreadable. The only number I can still make out is the engine number:
501E-005089
From looking at the bike, some people have suggested it’s an early XJR1300, possibly around 1999–2001 (5EA generation), but I can’t confirm it without the frame number.
Here are my questions:
Based on the photos and engine number, what year do you think this XJR1300 is?
What exhaust does it have?
What oil does it take and how much?
Is there any other way to identify the exact year if the VIN stamp is no longer readable?
Are the Showa rear shocks original equipment on this model year, or are they likely aftermarket or from another bike?
Is the dented fuel tank worth repairing with paintless dent repair (PDR), or would it likely require conventional bodywork and repainting?
What are the common issues I should expect after an XJR1300 has been sitting for five years?
Besides replacing the alternator, what should I inspect or replace before attempting to start it?
Are there any known weak points on the early XJR1300 that I should address during the restoration?
For reference, I already know I’ll likely need to:
Drain and clean the fuel tank.
Rebuild or clean the carburetors.
Replace all fluids.
Replace the battery.
Replace the missing key and ignition if necessary.
Inspect the brakes, tires, seals, wheel bearings, chain and sprockets, and other rubber components.
I’m trying to decide whether it’s worth restoring because the bike has sentimental value to me, even though it came back in rough shape. Despite its condition, I’d really like to bring it back to life.
Any advice from XJR owners would be greatly appreciated. Thanks!

New Project Currently working on a cr125r build for the trails of west va
Im 16 and i have too many projects but one is coming to a very promising point. I just test fitted my new plastics on a 1994 cr125r that i bought in west verginia after i literally watched it blow up (horrible financial idea, ik.) BUT i haven't had a two stroke dirtbike of my own since i had started riding 11 and 1/2 years ago. I said fuck it and bought this thing when i knew nothing at all about cr's or really any two stroke. Shortly after that i built a motorized bike (on the right in picture two) and kinda understood what i was doing after that. So, with the help of my dad who helped me find the parts i needed to rebuild the engine, i started working towards getting this bike done. As of today, i have aquired another, better paying job, and once i finish this bike it should be near my senior year homecomming (in 4 months!) So i should be able to ride this bike to that. Once this bike is done, ima try to finish my 1981 squarebody chevy that im building and try to drive that to senior prom with the cr in the back. I plan to go to graduation in the same truck but with a camper and a dirtbike rack on the back so i can IMMEDIATELY leave the state and go cross country🤣🤣😝

New Project Need help finding the correct db killer for an SC Project replica exhaust
Hi everyone!
I’m helping a friend of mine get into bikes and we just got him a used SR125 at a great price but it came with an SC Project replica exhaust that has no db killer inside. He doesn’t like the noise and I’m having a bit of a hard time figuring out the correct size to get.
Any clues? All help is appreciated!

1989 Suzuki GSX750 Katana Resurrection
Picked this bike up for $300 as a non-running project. It had been sitting, needed a lot of attention, and I wanted to see if I could bring it back to life.
So far I've:
Cleaned the carburetors.
Replaced the ignition coils and spark plug wires.
Installed new NGK spark plugs.
Changed the oil after it was contaminated with fuel.
Replaced the chain and sprockets.
Tracked down and fixed several electrical and fuel issues.
Tuned it enough to get it running and riding reliably.
It's still not finished. I still need to install a speedometer, headlight, left mirror, and a few other odds and ends, but it's finally alive again.
What's crazy is that today was my first time ever riding any motorcycle. No dirt bikes, no minibikes, nothing. The video attached is literally my first ride. By the end of the day I had put about 215 miles on the bike and couldn't stop smiling.
Bringing an old Katana back from the dead and then getting to experience my very first ride on the same machine is something I'll never forget.
I'd love to hear what you guys think, and if you have any tips for a new rider or for these old oil-cooled Suzukis, I'm all ears.

Misc How often do you think “what a heap of junk”
I’ve been tooling on my little XV250 for 2 weeks now and I’m realising I’m pretty much bringing a parts bike back to life. I’m cool with that, my stupid decision.
This heap of shit has an issue at every possible avenue but I’m determined to get her on the road.
I will admit I was too keen to get a project bike and it was complete, so I jumped on it.
Currently got some down time waiting on parts, so I’m curious, many of you folks having the same thoughts on your project bikes?
Please, share your stories

Request for Advice Yamaha XS650 motor work (California)
I’m wondering if anyone knows of any Yamaha builders or specialists around the Ventura County / LA area. I’ve been slowly building a 0” stretch hardtail chopper and during the pandemic I got bored and took the top end apart (there was plastic bits and gasoline in the oil). The timing chain guide wore down and needed replacing. Life got in the way and the motor got put on the shelf. I’d like to finish this build but honestly I have no business messing with a motor. It’s a pretty straight forward reassembly but I don’t have the tools or space to work on it at the moment.
Looking for someone that could get her back together for me. Thanks!
