Suzuki DR650 adventure build

Recently in 2023, I got a 2003 Suzuki DR650 as a Christmas gift for myself. The bike had approximately 5000 miles and looked decent for a 20 year old bike. The seller asked $3000 for it. Knowing that the bike being a Japanese will outlast other bikes by a long time, I bought the bike and set out to equip it to take on new adventures.

The bike looked good for being 20 years old.

Issues

There were a few issues with the bike as it is expected with an old bike.

  • Suspension was way too soft causing dangerous brake dives
    • Found later that the front fork was lowered as well
  • The engine was bogging at 2nd and 3rd gear
    • May be a carb issue, it was running lean
    • May be a worn clutch
  • Rear brake was almost not working
  • Seat was a akin to a wooden block causing painful ride experience
  • Brittle worn out plastics all around
  • Small 3.4 gal fuel tank with range less than 160 miles.

Mods List

To fix all the above mentioned issues and improve some other things on the process, I prepared a list and spent little more than the cost of the bike itself on the mods.

This expenditure was justified because most of the mods are required even for a 2023/2024 DR650 since the design has remained unchanged for a good 30 years or so. So rather than getting a $7000 2024 DR650 and then spending money on the mods, got a reliable 20 year old bike for cheap and invested the rest on the mods.

Most of them are from procycle.us, an Oregon based company with fantastic reputation for having almost everything for a DR650 and a good customer service. And few of the frame protection parts are from Xitomer, a Chinese company which makes quality parts for DR650.
