This was no doubt one of the most solid motorcycles I have ever owned. Mine had the jota head and the factory racing header and 129 was not the top speed. It high sided me at 50+ mph. and tumbled down the road. I road it home 650 more Mi. with the plastic and glass in gabage bags but the only real chassis damage were fork tubes that were bent about .070 in., not bad for an endo at speed. It also performed flawlessly in rain and snow and ice on that trip. The only problem I encountered was a week starter but I attribute that to the higher compression head and thick oil. Nothing a little run and jump couldnĀ“t cure.
