phb Posted May 31, 2006 Report Share Posted May 31, 2006 Hi im wondering if any one has heard any details of the the 2007 spec beta ive heard its going to be 2 stroke fuel injection and not modelled on the rev 3 any ideas out there Quote Link to comment Share on other sites More sharing options...
feetup Posted June 1, 2006 Report Share Posted June 1, 2006 did you mean 2 stroke fuel injection or 4 stroke fuel injection? Seems odd that they would make a major revision to the 2T motor at this point, if ultimately they need to go to a 4T design. It would be more cost-effective for beta to ride out another year or two on the existing rev-3 technology, until they have to change to a new motor & frame, etc. Personally, I'm very curious to see what Beta has in store for us with their 4T bike... I hope it is as fast-revving as the yamaha powered SY250F Taddy rode at the TTC in the USA... that bike sounded almost two-stroke like. Guess we'll have to wait a bit longer to find out.

stuessenhigh Posted June 1, 2006 Report Share Posted June 1, 2006 Correct me if Im wrong, but I THINK it still isnt DEFINATE that they will NEED to go to a four stroke?? I thought the jury was still deciding on that ruling?? Quote Link to comment Share on other sites More sharing options...

Going with FI on an otherwise rock-solid trials package makes sense and kills two birds with one stone, lose the 70's technology Mikuni AND probably comply with upcoming pollution standards using fuel injection. Like Stu said, they may not NEED to go through a complete re-build when the answer is a cleaner tailpipe through more precise fuel management. If it's true, sounds like a genius decision on Beta's part to me. Quote Link to comment Share on other sites More sharing options...
clarkp Posted June 1, 2006 Report Share Posted June 1, 2006 To top it all off, there is NO WAY a four-stroke motor from ANY manufacturer will fit into the existing Verlicchi frame / tank combo... the valve train puts it way up into the fuel tank. A four-stroke forces a complete frame re-design and that frame / tank is one of the strengths BETA possesses: superior rigidity. The REV package is too much of a good thing to shelve it all and start over... just scrap the POS Mikuni and source FI technology from Keihin like HRC did for the 4RT. Like Clouseau says, '...problem sol-ved...' Quote Link to comment Share on other sites More sharing options...
stuessenhigh Posted June 1, 2006 Report Share Posted June 1, 2006 mmmm...nice to read all these sensible comments rather than people just airing their preferences over 2 or 4 stroke. Personally I agree...would be great to leave the Rev as it is...BUT..with a fancy bit of fuel injection....COOL!!! Well...I'm certainly not smart enough to make guesses, so I guess I'll just wait and see..probably wont be long eh! Quote Link to comment Share on other sites More sharing options...
