Yamaha TRX850 Enthusiasts Forum

So you've bombed your TRX engine, you've got flatslides, cams, pipes, porting, head work etc etc etc, you're putting out 110HP reliably:

What's your top speed?

& how quick does it get there?

Not many around putting out 110 bhp MV, Overs TDM based OV15-A racer only made 115 bhp. With the right gearing that would go to around 170mph (YZF 750 box was fitted) but it was VERY light too remember.

107 to 108 bhp would appear to be the highest outputs achieved by most folk who do not have a company throwing big bucks at it.

I very very much doubt there is much around over a real 100bhp. And certainly not reliably.

OK, so there have been a few who can produce one off dyno charts (which in themselves are utterly fecking meaningless) but not many who can show their gains. I have dyno charts for mine showing a stock 72bhp right up to a peak of 103.2 - all done on the same dyno.

Anyhoo, to answer your question. On 17/42 gearing (with a 70 section front tyre - it is relevant )I have seen an indicated 150. My dyno charts tell me that actual top speed is also a shade over 150.

Not done standing quarters for a while but I'd be reckoning terminal velocity of circa 125 - high tens or (more likley) low elevens.

In real money, mine will stick with most 600s up until silly speeds

Yeah, I was being a bit fecetious, we'll say 100BHP.

That's good to know.

Thanks for the link Minchead, those bikes would have cost a pretty penny, no doubt.

150mph, right? So about 240km/h?
