After much testing and engine swapping we've found the pirahna 150 is a great "drop in" motor for the MadAss 125. Additional advantages are complete battery deletion and tons more power, all existing madass mods are applicable, so you don't have to start over, watch this spot for more details.
Welcome to Dr. Madass! The Doctor is the worlds first "Sach's Therapist" and is here to help you make a BadAss out of your MadAss. Follow along over the next two weeks and witness as our own Phil Waters and James Robertson take a MadAss cross country to show the vigor and durability of this little bike. Then, continue to follow as we post pictorial and video information on modifying the MadAss to meet it's full potential. We have been performing autopsies in the lab and have been fleshing out the good and the bad in the Madass performance parts world. Including a prototype of our own custom POC/HMF MadAss performance exhaust. Exciting things are to come. Check back often as the site develops into the most comprehensive MadAss resource. Sincerely, Dr. MadAss
