We are unable to supply these forks for Sur-Ron Electric Motorcycles. We have yet to assess them for tuning data and don't currently have it planned.
- We offer a calculated tuning service – using endless data acquired from hours of testing and data logging, we can make calculated and informed decisions on what settings, re-valving and modifications are suitable for you. Your suspension will be thoroughly tested with our dyno facilities and tailored to you and your riding style.
