Malossi Honda Contra Spring
Your transmission tuning is a big deal. If you are running a soft, or weak center spring, your transmission is changing too fast. This could be the difference of pulling wheelstands off the line, or your bike being a total dog until 15mph. I've seen it all too often.
Yellow or Red
Yellow is perfect for sport to midrace 72cc-80cc builds. Red is for race setups only!
