There are thosewho live and die by their 4-speeds today. So we developed the BAKER Ratchet Top 4-speed for all those who hail the venerable 4-speed.The external architecture of our cast (A356-T6) 4-speed transmission case was modeled after factory cases but includes an electricspeedo provision in the back and the traditional 4-speed gear drive provision in the front. Also, the loose rollers on the main drive gearwere replaced with a radial ball bearing. Case is available with 3 finishes; wrinkle black, polished, and raw (bead blasted).The detent in the Ratchet Top was migrated from the stock Fred Flintstone type to the snot-slick linear detent system for that smoothsnick-pop shift quality you come to expect from us.The N1 shift drums have a 0-down all-up shifting pattern, andeliminate any possibility of catching neutral on aggressive 1-2shifts. Neutral is below 1st. The N1 drum is also popular withhandshifting bikes where finding neutral without doubt or error iscritical to safety or riding/looking smooth.The N1 drum is also available for stock 4-speeds and for our newratchet top 4-speed.This is great for you hand shifters who want neutral at the bottom!No more missed shifts!Part No.4-155N1-KFITMENTBAKER N1 Shift drum kit For Stock 4-Speeds, 1952-1979 Ratchettop coversAvailable with many kicker cover options in many finishes; kicker and non kicker versions. BAKER Klassic Kicker Gears and bronze kickerpedal come standard on kicker transmission assemblies. Gearset is made with 8620 steel and gears ride on needle bearings, not brassbushings.
